Which coin do you have
Bitcoin.
which coin you do not have？
Everything else.
Greyscale is back, and they reopen bitcoin trust,bitcoin cash trust, ethereum classic trust,horizen trust,Litecoin trust.
Hold any of them?
Since most people here are retail investors, I would be surprised if there was at least 5 people here on Bitcointalk(out of hundreds of thousands) invested in any of Grayscale's crypto trusts.
