Some stocks are good for investing and others are better for trading. Bitcoin has become a popular trading instrument and may end up being at least somewhat uncorrelated with other asset classes. Currently, ProShares Strategy Bitcoin ETF (BITO) is a popular way to trade bitcoin (that uses bitcoin futures). Coming in June, the 2x Bitcoin Strategy ETF (BITX) will offer a leverage product for trading bitcoin. This could be a very useful instrument for those who like short-term trading.
