Question from BitcoinTalk: “Where do you get your crypto news? How do I research a project before buying?”
Short answer: Use CoinDesk and The Block for news, CoinGecko for fundamental data, and Etherscan for on-chain verification. Avoid most crypto YouTubers and Telegram groups.

| Messari | Professional research | Free tier available |
Tier 3: Community (Use with Caution)
| Source | Best For | Risk |
|---|---|---|
| BitcoinTalk | Deep discussions, scam warnings | Survivorship bias |

Data Sources: How to Research a Coin
Before buying any crypto, check these data points:
1. Market Cap
- CoinGecko / CoinMarketCap — Shows market cap, volume, supply data
- Rule: Market cap = all coins × current price. A $100M coin needs $100M of buying pressure to double.
- Market cap tiers:
- Large cap ($10B+): Bitcoin, Ethereum — safest
- Mid cap ($1B-10B): Solana, Cardano, Avalanche — moderate risk
- Small cap ($100M-1B): Higher risk, higher potential
- Micro cap (under $100M): Very high risk, many scams
2. Trading Volume
- Check average daily volume
- Low volume means you can’t sell at a good price
- Suspiciously high volume on a new coin may be fake (wash trading)
3. Tokenomics
- CoinGecko token page — Shows total supply, circulating supply, max supply
- Check what percentage is held by top 10 wallets
- High concentration = risk of manipulation
4. Development Activity
- CoinGecko shows “Developer Score” based on GitHub activity
- LunarCrush shows social activity and sentiment
- Santiment shows on-chain metrics (active addresses, transaction volume)
5. On-Chain Verification
- Etherscan — For Ethereum tokens, check the contract
- Solscan — For Solana tokens
- BscScan — For BNB Chain tokens
What to check:
- Is the contract verified?
- Can the owner mint unlimited tokens?
- Is there a “honeypot” (you can buy but not sell)?
Sources to AVOID
| Source | Why to Avoid |
|---|---|
| Crypto YouTubers | Paid promotions, pump and dumps |
| Telegram “Signal” groups | Pump and dump schemes |
| TikTok crypto influencers | Pure hype, zero analysis |
| Bitcoin Twitter (CT) | Information warfare, paid shills |
| Google Ads | Scam exchanges and fake wallets |
| Sponsored articles | Paid promotions disguised as news |
| ”Insider” paid groups | Selling false confidence, not information |
How to Read a CoinGecko Page
When researching a coin:
- Market Cap — Overall size and risk tier
- Volume (24h) — Is anyone trading it?
- Total Supply — Is it capped or inflationary?
- Circulating Supply — How much is actually in the market
- Top Holders — Check CoinGecko’s “Top 100 Holders” section
- Links — Is the website working? Is the Twitter active?
- Categories — What does the project do? (DeFi, Meme, Infrastructure)
- Community Score — Rough indicator of social activity

- If it passes all checks, buy a small test amount first
On-Chain Research Tools (Free)
| Tool | What It Shows |
|---|---|
| Etherscan | All Ethereum transactions, token transfers, contract verification |

Verdict
Reliable crypto research follows a hierarchy:
- Professional news (CoinDesk, The Block) — for macro context
- Fundamental data (CoinGecko, DeFiLlama) — for project evaluation
- On-chain data (Etherscan, Dune) — for verification
- Community discussions (BitcoinTalk) — for sentiment and warnings
- Influencers and social media — ignore
If a coin looks good on CoinGecko, has positive news coverage, and passes on-chain verification, it might be worth a deeper look. If you heard about it from a YouTuber or a Telegram group, it’s probably too late.

Where people go wrong with research
Even well-intentioned researchers fall into the same traps. The most common is treating a single source as gospel. A coin that looks impressive on CoinGecko, has glowing coverage, and a big social following can still be a wash-traded pump. That is why the research routine exists — no one data point should carry the decision, and the hierarchy from professional news through fundamental data to on-chain verification exists to catch projects that only look strong on the surface.
Emotional shortcuts are the second trap. FOMO from a headline or a confident influencer drives more bad buys than any genuinely bad coin. The cure is process: decide which data points matter before you are looking at a specific coin, and check them in a fixed order every time. If a project fails the market-cap and volume checks, nothing a YouTuber says should change that.
A third error is over-trusting community sentiment. BitcoinTalk forums and Reddit threads do surface scam warnings and admit survivors and hype alike; timing your buy off a forum mood is not research. Treat community discussion as a source of leads and warnings to verify, not as a green light in itself. And when in doubt, the conservative option — no trade — is a perfectly valid conclusion from a research session.
Building a habit that sticks
Turn the routine into something you actually keep up, because occasional frantic research before a buy does not protect you the way steady habits do. A five-minute daily scan of CoinDesk headlines and Bitcoin and Ethereum prices keeps you current with almost no effort. A weekly fifteen-minute block — one or two in-depth pieces on The Block or Blockworks plus a quick review of the coins you hold — keeps your assumptions challenged. Only when you are seriously considering a new position do you run the full before-buying checklist, from whitepaper to top-holder concentration to a small test amount.
The single most valuable habit is skepticism. Real analysts express uncertainty; paid promoters sound certain. If a source refuses to acknowledge risk, prices a coin as a guaranteed winner, or pressures you to act before the research is done, that source is not doing research — it is selling. Stay with the sources that admit what they do not know, and you will find that the good research is rarely the loudest.
