you could be dead on right... that guru of Crypto (Altucher spelling?) recently stated that just like the .com's there will be hundreds of crypto's but only a few will survive and do well...ala Amazon.com, etc...
GBTC is down 25% in one day, BTC dropped from 11400 to 9300.
Did I say one day? I meant in 6 hours.
GBTC is not levered, it trades at a large premium to NAV. Big fluctuations happen when people start to second guess paying such an ridiculous premiumYeah but in that time frame BTC also went up almost 50%, from 8K to 12K. Since GBTC is somehow leveraged, a doubling is not out of the ordinary. But today a 1% down move in BTC caused a 25% drop off in GBTC? Maybe as you said it was just the overbought state of GBTC, maybe something else...
