GBTC is going to be the world's first publicly traded Bitcoin fund. Barry Silbert launched this thing in 2013 and they found a sneaky backdoor to putting a "Bitcoin fund" on a public exchange by publicly selling shares that have been held for 12+ months on an "Over the counter" market (not a top-tier one such as NYSE or NASDAQ). It is not officially an ETF (which is what the Winkle Twins are going for on NASDAQ), but it functions in much in the same way (with pretty hefty fees might I add). Effectively, each GBTC share is worth 0.1 Bitcoins, and it is set to start trading sometime this week, or so we are led to believe by Barry Silbert's Twitter account.
