Invested in it in the late 2017 boom, was left holding bags which were down 80% from all time high. But kept believing in the tech and kept buying small amounts all the way until July of this year when I finally broke even. That's when I took a gamble and put all my IRA into GBTC (risky bet which could have back fired). Ended up tripling my IRA balance due to the recent run-up to 23k. So I can say I'm very much in profit but it involved immense risk taking.
