Coin Profiles

Coin Profiles

There are thousands of cryptocurrencies, and the noise around them is deafening. These profiles cut through it — a plain-language look at each major coin: what it actually is, what it’s for, and the honest risks. No price predictions, no hype, no “next 100x.” Just what the coin is and isn’t.


A note on these profiles: a coin being listed here is not a recommendation to buy it. Inclusion just means it’s well-known enough that a beginner is likely to encounter it and want to understand it. Every profile includes the honest risks. This is education, not financial advice — always do your own research.


Start here: the two foundations

  • Bitcoin (BTC) — The original cryptocurrency, and still the one everything else is measured against.
  • Ethereum (ETH) — The “world computer” that powers smart contracts, DeFi, and much of crypto.

Other major coins

  • Solana (SOL) — The fast, low-cost platform — and its history of outages and volatility.
  • XRP — The payments-focused coin tied to Ripple, and its now-resolved legal saga.
  • Cardano (ADA) — The research-driven, “slow and careful” smart-contract platform.
  • Polygon (POL) — The Ethereum-scaling network — and its MATIC-to-POL token change.
  • Chainlink (LINK) — The “oracle” network that feeds real-world data to smart contracts.
  • Litecoin (LTC) — The veteran “digital silver” payment coin, and the relevance question.
  • BNB — Binance’s own coin: what it’s used for, and the honest risks of owning it.

Stablecoins & memecoins

  • Tether (USDT) — The largest stablecoin and the “digital dollar” of trading — plus its reserve questions.
  • USD Coin (USDC) — The regulated, transparency-focused dollar stablecoin — and its 2023 depeg.
  • Dogecoin (DOGE) — The original joke “memecoin,” and a lesson in hype-driven value.
  • Shiba Inu (SHIB) — The #2 memecoin, and the “cheap coin” supply illusion.

More coin profiles are on the way, each following the same honest format: what it is, what it’s for, and the risks.
