Ouch! Maximum pain.
Dude sells 640 BTC for $5,807.53 each in 2017, nets $4 million fully doxxed in his Coinbase account, underreports his capital gains tax and thinks he'll get away with it.
He #FAFO'd and got 2 years in prison.
Just a reminder, don't bother with this headache, just don't sell and you'll be fine! If he did he would be up so biggly its redonk, his total 1,366 BTC would be worth $146 million right now
Bro got cooked for what is relative chump change
