Grayscale Bitcoin Trust (GBTC)

Why the Huge Premium for GBTC?
Potential investors are likely wondering why GBTC shares can be found at such a high premium over Bitcoin. The issue seems to lie in supply and demand. While Bitcoin demand has skyrocketed, GBTC has kept its shares outstanding close to 1.7 million in the two years that it has existed. In fact, the ETF seems unlikely to change the number of total outstanding shares in the future, according to the company's head of research, Ihor Dusaniwsky. He explains that "with the operational risk of buying and holding actual Bitcoins to support ETF creation very high, and difficult and expensive to insure, it is unlikely that GBTC's outstanding share amount will climb above 1.7 million anytime soon."
