GBTC’s premium is determined by supply and demand. One can check out its discount/premium to NAV everyday. But most importantly is its price action. When bitcoin was traded around $3,000, GBTC was at $330. Today it closed at $1,636. And that is down from $3,523 just about a month ago. The point is, if you buy low, there is still nice profit to be made, regardless of the premium you paid. Crytocurrency has lost its initial purpose and intent, and become a big speculative game. I hope those who sold their mcc holdings and got into the game, made some good money and got out already. This is the most volatile price action I I've seen since the year 2000 dot com bubble.
