Buy Hodl Sell is an independent education and research site for people trying to understand cryptocurrency systems without starting from a sales pitch.
The site has three connected parts:
- Articles explain wallets, transaction models, protocol upgrades, privacy, tokens, and network capacity.
- The Cryptionary defines technical and community terms in plain language, with related concepts for further reading.
- Tools turn live or modeled data into something you can inspect: transaction flow, CashToken activity, protocol upgrades, and blockspace pressure.
Each part should make the others easier to use. An article can introduce a concept, a glossary entry can clarify it, and a tool can show how it behaves.
What the site covers
The editorial focus is Bitcoin, Bitcoin Cash, wallets, UTXO systems, and the infrastructure around them. Other networks appear when a comparison helps explain a real design choice, such as account-based smart contracts or proof-of-stake consensus.
Coverage is descriptive, not an endorsement. Cryptocurrency protocols make different tradeoffs, software changes, and live data sources can fail or disagree. Where a claim depends on a specification, release, or external service, we aim to link the primary source and state the limitation.
Start with the question you have
If you are setting up a wallet, begin with Crypto Wallet Basics. If a word is unfamiliar, search the Cryptionary. If you want to observe the networks directly, open TX::Watch, TokenWatch, or Blockspace Lab.
The tools are educational views, not trading systems or complete blockchain indexes. Session totals only cover activity observed while a page is open, external APIs can be delayed, and simulations simplify real node and miner behavior.
Corrections are part of the work
Protocol documentation, wallet behavior, and ecosystem conventions all change. If a page is unclear, outdated, or technically wrong, send the page URL and suggested correction through the contact page. Good educational material is maintained, not merely published.
