Crypto position & risk calculator

Size the coin before you click buy.

A learning tool for crypto trades. Tell it how big your account is and how much you are willing to lose, and it works out how many coins to buy, what you stand to make or lose, and the price you need just to break even after fees. It only gathers and explains data - it never places a trade.
