Best Crypto News Sources: Where to Research Before You Buy

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.

News Sources (Ranked by Reliability)

Tier 1: Professional Crypto News

CoinDesk is the closest thing to a Bloomberg for crypto. They break legitimate stories and have editorial standards. Read daily.

Tier 2: Aggregators and Data

Tier 3: Community (Use with Caution)

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

How to Read a CoinGecko Page

When researching a coin:

1. Market Cap — Overall size and risk tier
2. Volume (24h) — Is anyone trading it?
3. Total Supply — Is it capped or inflationary?
4. Circulating Supply — How much is actually in the market
5. Top Holders — Check CoinGecko’s “Top 100 Holders” section
6. Links — Is the website working? Is the Twitter active?
7. Categories — What does the project do? (DeFi, Meme, Infrastructure)
8. Community Score — Rough indicator of social activity

Building Your Research Routine

Daily (5 minutes)

• Scan CoinDesk headlines
• Check Bitcoin and Ethereum price

Weekly (15 minutes)

• Read 1-2 in-depth articles on The Block or Blockworks
• Review your portfolio on Zerion
• Check for major developments in coins you hold

Before Buying Any Coin

1. Check market cap and volume on CoinGecko
2. Read the whitepaper (focus on the problem and solution)
3. Check GitHub for recent development activity
4. Search “[coin name] scam” on Google
5. Check top holder concentration
6. Read the latest 5 news articles about it
7. If it passes all checks, buy a small test amount first

Verdict

Reliable crypto research follows a hierarchy:

1. Professional news (CoinDesk, The Block) — for macro context
2. Fundamental data (CoinGecko, DeFiLlama) — for project evaluation
3. On-chain data (Etherscan, Dune) — for verification
4. Community discussions (BitcoinTalk) — for sentiment and warnings
5. 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.
