Hello! We’re now ready to start promoting our free Telegram crypto & stocks channel and are looking for someone who can help us grow it properly and consistently.

We are a very new channel, so we would appreciate a clear strategy rather than just purchasing subscribers.

Could you please provide us with a 6-month marketing and growth plan covering:

- How you would start promoting a brand-new Telegram channel
- What you would need from us before starting
- Which promotion methods you recommend (Telegram ads, placements in other channels, Meta ads, influencer/channel collaborations, etc.)
- Your recommended advertising budget per month
- Your management/service charges
- Expected real subscriber growth each month
- Estimated cost per genuine subscriber
- Which countries/audiences you would target
- How you make sure subscribers are relevant to crypto, stocks and trading
- Expected views and engagement as the channel grows
- How you track results and provide reports
- What content/posting strategy you recommend alongside the advertising
- How you would eventually help us convert free subscribers into paid members

Please give us realistic expectations rather than guaranteed or inflated numbers. We are interested in building a long-term, active community, not simply adding fake or inactive subscribers.

If possible, please break the proposal down into Month 1 through Month 6, showing the estimated ad spend, your fee, expected subscriber growth, and the main strategy for each month.

We are ready to start, so please let us know what information or access you need from us first.

## Social Media Expert Wanted — Fintech & Digital Assets

We’re preparing to launch a new financial technology platform focused on automated market execution and yield infrastructure across digital assets and global markets.

Our goal is simple: remove unnecessary complexity from trading and provide users with transparent, system-driven access to financial opportunities—built around disciplined algorithmic execution, not hype or speculation.

We are looking for a skilled **Social Media Expert** to help shape our public presence ahead of launch and support long-term community growth.

## The Role

You will be responsible for turning complex financial technology, market concepts, platform updates, and leadership content into clear, engaging social media communication.

You will work closely with the CEO, technical team, and project leadership to build a trusted brand across platforms such as X/Twitter, LinkedIn, Telegram, Discord, YouTube, TikTok, and other relevant channels.

This is not a meme-coin promotion role. We want thoughtful, credible communication that attracts the right audience and builds lasting trust.

## Key Responsibilities

- Develop and manage the social-media strategy before and after public launch.
- Create a consistent content calendar across key channels.
- Turn weekly leadership updates, interviews, AMAs, and product developments into high-quality posts, threads, short videos, captions, and community announcements.
- Help explain automated execution, yield infrastructure, market activity, and risk in clear, accessible language.
- Grow and engage a real community without relying on misleading claims, artificial engagement, or hype.
- Coordinate announcements, launches, partnerships, media appearances, and educational campaigns.
- Monitor community sentiment and identify recurring questions, concerns, and opportunities.
- Support live community calls, Twitter/X Spaces, AMAs, and video releases.
- Track content performance and provide practical reporting on growth, engagement, reach, and conversion.
- Protect the platform’s reputation by ensuring messaging is accurate, responsible, and consistent.

## What We’re Looking For

- Proven experience managing social media for fintech, crypto, trading, SaaS, technology, or finance-related brands.
- Strong understanding of X/Twitter, LinkedIn, Telegram, Discord, YouTube, and short-form video platforms.
- Excellent written English and the ability to write clearly, confidently, and professionally.
- Ability to simplify technical or financial subjects without making unrealistic promises.
- Strong content instincts: you know what makes people stop, read, watch, share, and participate.
- Comfortable working with founders and leadership who are public-facing on video and in live communities.
- Organised, proactive, and capable of working independently in a fast-moving environment.
- A genuine understanding of reputation management, risk communication, and trust-building in financial markets.

## Strong Advantages

- Experience in digital assets, DeFi, algorithmic trading, fintech, market infrastructure, or investment platforms.
- Video editing, graphic design, motion graphics, or short-form content experience.
- Experience growing a Telegram, Discord, or X/Twitter community.
- Experience supporting founder-led brands or public executives.
- Familiarity with analytics tools, content scheduling tools, and community-management platforms.
- Ability to create educational threads, explainers, scripts, and campaign concepts.

## What Success Looks Like

You will help establish the platform as calm, transparent, educational, and trustworthy.

Rather than chasing attention at any cost, you will build an audience that understands what we are creating, how the platform works, the risks involved, and why our long-term approach matters.

## How to Apply

Please send:

- A short introduction about yourself and your relevant experience.
- Examples of social accounts, campaigns, threads, videos, or communities you have managed.
- Your experience in fintech, crypto, trading, or financial services, if applicable.
- Your preferred monthly rate or hourly rate.
- A brief outline of how you would approach the first 30 days of our social-media launch.

We are seeking an experienced Full-Stack Web3 Developer to create a crypto investment platform using Next.js, Python/FastAPI, and Ethereum/EVM smart contracts. The platform will enable users to connect their crypto wallets, authenticate via wallet signature, and interact with smart contracts. Key features include a responsive Next.js frontend, Python/FastAPI backend, Ethereum/EVM smart contracts, wallet integration, and user dashboard. Smart contracts must adhere to best practices, including access control and reentrancy protection. Please provide examples of previous Web3/DeFi projects, estimated timeline, budget, and recommended EVM network.

About the Opportunity

We are a forward-looking Web3 organization focused on developing high-impact onchain ecosystems. Our current roadmap includes the launch of a staking contract platform and an onchain gaming infrastructure, both seamlessly integrated with our Metaverse token ecosystem across leading EVM-compatible chains. To accelerate this vision, we are seeking a senior-level Blockchain Software Engineer with deep technical expertise in Solidity, smart contract architecture, and backend systems.
This is a remote, flexible engagement with a clear pathway to a long-term partnership, contingent upon demonstrated performance and mutual fit.


Core Responsibilities

- Architect, develop, and deploy secure and gas-optimized Solidity smart contracts for staking mechanisms and gaming platform utilities.
- Design and maintain backend infrastructure to support staking logic, token interactions, and platform-wide functionality.
- Collaborate closely with the engineering team to ensure seamless integration between onchain components and web-based frontend/backend systems.
- Provide bi-weekly progress reports to the Project Manager, ensuring transparency and alignment with project milestones.
- Conduct thorough code reviews, testing, and security audits to uphold best practices in blockchain development.


Required Qualifications

- Proven professional experience in Solidity development and smart contract deployment on EVM-compatible chains (Ethereum, Polygon, BSC, Arbitrum, etc.).
- Strong understanding of staking protocols, tokenomics, and DeFi primitives.
- Proficiency in full-stack web development (JavaScript/TypeScript, Node.js, React, or equivalent) to support dApp integration.
- Familiarity with version control systems (Git/GitHub) and CI/CD pipelines.
- Excellent communication skills, with the ability to articulate technical decisions and progress to both technical and non-technical stakeholders.
- Self-motivated, detail-oriented, and capable of working independently in a remote environment.


Compensation & Benefits

- Hourly Rate: $75 – $120/hour (commensurate with experience, location, and demonstrated expertise)
- Role Type: Remote – Full-time (30–40 hrs/week) or part-time, based on your preference and availability
- Trial Engagement: 1–2 weeks of paid onboarding at full rate to validate skills and collaboration fit
Long-Term Contract: Upon successful completion of the onboarding stage, we are pleased to discuss a long-term contract tailored to your contribution level
- Growth Potential: High-performing candidates will be considered for extended collaboration as we scale our platform and ecosystem

For context, well-funded protocols pay senior Solidity engineers $195K–$255K base salary plus token grants in full-time roles, translating to comparable freelance rates of $100–$150/hour for top-tier independent contractors . Complex DeFi or protocol-level builds typically run $30K–$150K+ per project.


Our Hiring Process

We have designed a structured, transparent, and merit-based evaluation process to ensure alignment with our technical standards and team culture:
1. Technical Skill Assessment – A practical GitHub-based task will be shared to evaluate your Solidity and backend engineering capabilities. Full instructions are provided in the accompanying README file.
2. Interview Rounds – Following the assessment, selected candidates will participate in 2–3 rounds of interviews, covering technical depth, architectural thinking, and cultural fit.
3. Paid Onboarding Stage – Shortlisted candidates will be invited to a 1–2 week paid trial engagement. This phase allows us to collaboratively validate your skills, working style, and integration into our development workflow.
4. Long-Term Engagement – Upon successful completion of the onboarding stage, we are pleased to discuss a long-term contract tailored to your availability and contribution level.


Application Instructions

- To apply, please submit your Upwork proposal including:
- A concise summary of your relevant experience, particularly with Solidity, staking protocols, and EVM-based projects.
- Links to your GitHub profile, relevant repositories, and/or deployed smart contracts (mainnet deployments with audit history are highly valued).

UX/UI review of a live market visualization web app

wtf.market is a real-time stock and crypto visualization tool. Instead of tables, companies render as live bubbles that move and resize with the market. It also scores companies against classic investing books (Graham, Buffett, Lynch, Greenblatt) and explains each verdict in plain language.

It's live and it works, but I'm a backend engineer, and it's never had a designer's eyes on it. I'd really value an experienced outside perspective.

What would help most:

1. How does it feel to land on this for the first time?
2. Where might people get lost or lose interest?
3. Is the information hierarchy right — am I leading with the wrong things?
4. Prioritized recommendations, so I know what to tackle first

A bit unusual: it isn't a standard dashboard. It's a WebGL canvas with physics-driven bubbles, so the usual layout conventions only half-apply. Inspired by https://cryptobubbles.net/ and https://banterbubbles.com/home.

How I work: feel free to be candid, I'd genuinely rather hear the hard notes than the polite ones

Job scope/expectations: in-depth website design review

First step: I'd love to hop on a short call if that's an option to discuss the project vision, context, roadblocks, etc.

Looking for a rockstar UX/UI designer who has designed forex and crypto trading apps (mobile and web).

Please send screenshots of your work to make it easier for review. I might not have time to view your entire Dribbble portfolio.

Share your best work :-)

Our properties include:

LeapRate.com — B2B industry journalism since 2010, read by broker C-suite, compliance officers, payment providers and fintech leadership
AskTraders.com / ForexTraders.com — retail and semi-pro trader research, global English

Plus 24 more brands across forex, stocks, fintech, crypto and trader education

Our work is cited by WSJ, CNBC, Yahoo Finance, Investing.com, Business Insider and Euromoney, and indexed by Google News, Bing News and Apple News.

What we're hiring for

We want a media sales professional to own commercial revenue across the network. Part-time, ongoing, with genuine upside — not a one-off project.

You already know this industry. You've walked the floor at iFX EXPO or the Finance Magnates summits. You know the difference between a liquidity provider and a white-label platform vendor, you know a broker's affiliate manager and its PR lead are two different buyers with two different budgets, and you know who actually signs off spend. That knowledge is the job.

What you'll be selling

Real products with real ticket sizes — this is not a £150-press-release desk:

Product Price
Featured & Verified (flagship: placement on 4 sites, editorial review, Verified badge, directory listing, awards entry) £9,000 / year
Site takeover — AskTraders.com or LeapRate.com £10,000 / month
Site takeover — ForexTraders.com or BrokerDeal.de £6,000 / month
Full network takeover (all four) £28,000 / month
Directory listing — Market Leader £4,000 / year
Directory listing — Premium £1,500 / year
Detailed broker review, per property, any of 8 languages £1,900 each
Editorial placements From £700 per property
Awards, additional category £1,000 each
Display — leaderboard / half-page / in-article / MPU / sticky From £600–£1,500 / month
Press release — single site / wider network / full syndication £150 / £700 / POA
Social coverage, push notifications £300 each
Email marketing £0.10 per subscriber
Recommended Brokers List 2026, newsletter sponsorship, lead gen (CPA/CPL/hybrid) POA

Bespoke and multi-site packages are priced by our team, so you're never boxed in by the card.

Who buys

Two distinct buyer types, and you'll work both:

B2B / industry — liquidity providers, trading platform and technology vendors, payment and PSP providers, regulatory and compliance consultancies, law firms serving the sector. They buy LeapRate.com visibility, directory presence, press and thought leadership.
Retail acquisition — brokers' affiliate, acquisition and marketing teams buying comparison-table placement, reviews, takeovers and lead gen across AskTraders, ForexTraders, the DACH sites and TheBull. This is performance-adjacent budget and usually the larger pot.

Your responsibilities

Build and own a qualified pipeline across both buyer types
Run full cycle: outbound, discovery, proposal, negotiation, close
Lead with the annual and monthly recurring products — Featured & Verified, directory, takeovers, retainers — rather than one-off press releases
Upsell and renew existing partners; build multi-site and multi-language packages
Represent the network at industry events where it makes sense (attendance supported separately)
Keep CRM current, report pipeline weekly
Feed back market intelligence: what buyers want, what competitors charge, where our card is mispriced

What we need from you (non-negotiable)

A live contact book in the forex / CFD / online trading industry. The single most important requirement. If you haven't sold to, or worked at, brokers and industry vendors, this role isn't for you.
3+ years in B2B media sales, affiliate/partnership sales, sponsorship sales, or broker-side business development
Demonstrable history of closing four- and five-figure advertising, sponsorship or partnership deals
Fluent, credible written and spoken English — you'll be emailing C-level readers of publications they respect
Genuinely self-directed: remote, independent, reports on their own pipeline without chasing

Nice to have

Background at Finance Magnates, FinanceFeeds, FX Empire, Investing.com, Ultimate Fintech, or a comparable publication or event organiser
Affiliate / performance marketing background , we run CPA, CPL, hybrid and rev-share alongside fixed fee
German two of our properties are DACH-facing and that market buys well
Arabic, Spanish, Italian, Japanese, Malay or Indonesian — we publish in 8 languages and sell into all of them
Existing relationships with acquisition or affiliate managers at tier-1 and tier-2 brokers

Compensation

Monthly retainer plus performance commission. We want someone invested for the long term, not chasing one-off wins.

Retainer: competitive, contracted through Upwork, set against your experience and the strength of your network
Performance element: additional performance-based compensation on revenue you generate, agreed in writing before you start

Given the ticket sizes above, this is a role where the performance element should be the larger number within a few months. Tell us in your application what structure works for you we'd rather hear your number than guess it.

How to apply

Please don't send a generic proposal, we won't read past the first line. Answer the screening questions specifically, and open your cover letter with the single largest advertising, sponsorship or partnership deal you have personally closed in this industry, and who it was with.

Hello, Sergey!
As I am fulltime-employed in a hospital and been trading as retail trader beside my job I'm looking for time-saving scalping strategies...
I want to ask you if you could fullfill me a "backtesting-only" task concerning the following 2 scenarios:
I only want to take a trade after completion of the 2nd 5min-candle after US-market-open:
(1) go long if the last candle closed above the first 5min range - and vice versa in opposite direction (with the trend)
(2) if the 2nd candle broke the range of the first candle (either long or short) but then closes within the range - take the reverse trade.
Condition: TP of 25 ticks, close the trade within the 11th minute after market open, SL: 150 ticks.
The strategy's strenght should be the high win-rate versus the bad risk-reward-ratio. In my experience the SL is only reached seldom over 1 month (another argument could be not to trade in days with economic news ahead, but this could be another study)....my aim is to prove long-term profitability (e.g. 6 months? 1 year?) and therefore backtesting-data.
Please, write back if you want to do the backtesting and how much would you charge?
Cheers, looking to reading from you
