The ProShares Bitcoin Strategy ETF goes by the ticker name of BITO.Here are a few things to know about BITO:– The bitcoin-linked ETF began trading on the NYSE ARCA exchange on October 19 this year.– Investors can buy shares of BITO directly through the fund company or through a brokerage.– Since ETFs are investment securities traded on an exchange like stocks, the BITO ETF provides simple, indirect access to this cryptocurrency for retail investors.
