yes. and even if blockchain analysis isnt that good now, it will be.

i mentioned upthread i always pull 20% more on sells so its already in fiat for taxes. i dont touch it, only cash it in when the man wants his tax.

also i  put on my tax returns the stuff i buy through payment processors and stores that take btc directly. as they are taxable events and need to be reported too.

now i probably could of got away with not reporting newegg or whatever purchases, but im sure glad i did. you do NOT want the IRS as your enemy.
