CryptoTools

What is CryptoTools?

CryptoTools — https://CryptoTools.tech — A growing suite of 30+ free, single-purpose crypto & finance tools. Three families: calculators (Bitcoin DCA backtest, profit/P&L + tax, mining, portfolio/tax CSV, staking, leverage, liquidation, position size, impermanent loss…), converters (gwei↔ETH + gas fee, satoshi↔USD, hashrate), and a privacy-first cryptography toolkit that runs 100% in your browser — nothing is ever uploaded (SHA-256/keccak hashing, AES, RSA & key generators, BIP39 seed phrases, HD wallet addresses, JWT decoder, plus EVM/ENS/EIP-712 dev tools and more). Plus interactive Bitcoin data studies (DCA backtests, "what if you missed the best days", a monthly-returns heatmap). No sign-up, no tracking, no paywalls; pure static site with sub-second loads; works in 10 languages; every tool is embeddable. For traders, builders, and the privacy-conscious who want a fast answer without a bloated SaaS dashboard.
