Had at least 50 clients with crypto.  If using services like CoinTracker (from CoinBase) or RobinHood Crypto then it's just another 1099-B with no issue.  If from some "lesser" company then it's just a date-order listing of buys and sells and impossible to work with - you can't match buys and sells since it's not buy 100 shares and sell 100 shares.  Then I tell them - can't do it, unless it's only a couple in a year and that's easily tracked.
