If you'd bought back then, what would it be worth today?

Pick a coin, an amount and a date. The numbers use real daily closing prices, not estimates.

What-if vs. DCA

What if puts the whole amount in on one day and holds. It shows the best and worst of timing a single buy.

DCA (dollar-cost averaging) buys the same dollar amount on a schedule, every week or month. It smooths out the price you pay, so you buy more coins when prices are low and fewer when they're high.

How the numbers work

Each buy uses that day's closing price in US dollars. Today's value uses the latest traded price. Trading fees, taxes and staking rewards aren't included, so real results would differ a little.

Price history comes from the public market data of Bitstamp and Coinbase. Some coins only have data from the date they were listed there.

Not financial advice

This tool shows what happened in the past. Past prices don't predict future ones, and crypto can drop fast. Only invest what you can afford to lose, and do your own research.
