Hold My Bitcoin

What does Hold My Bitcoin do?

Free bitcoin calculators on real past prices: if I'd held, DCA vs lump sum, sats tracker, halving countdown. No sign-up, no ads, runs in your browser. Hold My Bitcoin is a set of free bitcoin calculators that use real daily closing prices back to July 2010. Pick a date and an amount to see what it would be worth if you'd never sold, compare your trades with just holding, or test DCA against a lump sum. There's a sats tracker and converter, price on any date, a halving countdown and a list of every big drawdown and how long it took to recover. A live page shows market stats, a BTC vs ETH/SOL/XRP/BNB compare chart and the mempool, and an indicators section covers Pi Cycle, the 200-week average, Mayer Multiple and log bands. There's also a "bitcoin is dead" page with 143 obituaries we checked. Everything runs in your browser, with no sign-up and no ads. Past data only, not advice.
