BobLawblaw and Searing haven't got real jobs, they both retired using their trading mining profits. I don't think that makes them parasites, it makes them the kind of winners we all want to be.
Can't speak for Searing, but I mined 90% of my BTC holdings, before selling my ASICs off in late 2015, for more BTC.
Bought a few small dips with fiat for shits and giggles, and converted a bunch of BCH->BTC when the fork happened to considerably boost my BTC holdings.
I've been HODLing for years. Long term gains taxed at 23.8% using FIFO accounting, muthafuckahs !!!

Also, looks like the apocalypse got called off.
YAY WEEKEND RALLY ! (?)
EDIT: Adding insult to injury, I'm effectively paying tax twice on Bitcoin. I owed and paid tax on the fiat value of the coin when it was mined, and owe tax again when selling. Cries.
