Negative premium is becoming a thing in GBTC: yesterday it hit -11%.

That makes the shares in the secondary market quite a bargain!
But I am a little bit worried by now: where this selling pressure is going to? Flowing to another "ETF"? outright selling?
Also, from the spreadsheet: what is going o happen when those massive quantities of locked shares become freely tradable?

Also from your other graph % of locked shares is currently at 36,5% which is at the same level as it was in Sept 2020 when BTC price was around $10k. Still high, but will keep going down everyday the primary is closed/fund is trading at discount. At this rate we should be under 25% of locked shares by May 10th, and under 20% by May 24th, so might see discount till May after that things should come back to normal
