Are You Ready to Decode the Market? 🚀
Flappy DAO is on the hunt for a Crypto Analyst who can turn raw blockchain data into actionable alpha. If you’re an OG in the crypto space—someone who thrives on charts, metrics, and uncovering hidden opportunities—this role is tailor-made for you.
As a Crypto Analyst at Flappy DAO, you’ll be the eyes and ears of our trading team, providing deep insights into market trends, token movements, and emerging projects. Think you’ve got what it takes to become the ultimate data wizard? Let’s dive in.
What You’ll Be Up To (Your Mission):
Analyze On-Chain Data: Dig into transaction volumes, whale activity, wallet distributions, and other key metrics to identify trends and predict price movements.
Monitor Market Sentiment: Track social media, news outlets, and community discussions to gauge FOMO/FUD cycles and their impact on the market.
Provide Trading Insights: Collaborate with our traders to deliver actionable recommendations based on your analysis.
Track Emerging Projects: Identify promising tokens, DeFi protocols, and NFT collections before they hit mainstream radar.
Leverage Exclusive Tools: Access proprietary datasets and analytics platforms (e.g., Glassnode, Dune Analytics, Santiment) to enhance your research.
Why Flappy DAO Slaps for Analysts:
Alpha Access: Get insider signals, exclusive tools, and early access to market-moving data.
Profit Sharing: A slice of the pie goes to you. We reward performance because we believe in eating what we cook.
DAO Vibes: Be part of an elite crew shaping the future of Web3. Your voice matters here—we’re all builders.
Flexibility: Work remotely and manage your own schedule while staying aligned with DAO goals.
What We’re Looking For (The Real Deal):
We don’t want just anyone—we want someone who lives crypto. Here’s how you prove it:
Proven Track Record: Show us your history as an active participant in the cryptocurrency market. Whether it’s through successful trades, contributions to DeFi projects, or involvement in DAOs, we need proof that you’re legit.
Examples: Links to your DEX trades, wallet activity, or past roles in other protocols.
Deep Market Knowledge: Understand the nuances of both centralized (CEX) and decentralized (DEX) exchanges. Know the difference between AMMs, order books, and dark pools—and why they matter.
Analytical Wizardry: Proficiency in SQL, Excel, Tableau, or similar tools for crunching data. Bonus points if you’ve used blockchain analytics platforms like Glassnode, Santiment, or Dune Analytics.
Community Engagement: Active participation in the Web3 space isn’t optional—it’s essential. Show us your Discord presence, Twitter threads, or forum contributions that demonstrate your passion for the industry.
How to Stand Out (Bonus Points):
Experience analyzing high-volatility assets like meme coins and understanding their unique dynamics.
Contributions to open-source DeFi projects or previous work with DAOs.
A portfolio showcasing successful market analysis or predictive modeling.
