The primary reason investors put their money into public crypto mining stocks is to act as a proxy for investing in bitcoin, as many institutional investors are hesitant to invest directly in cryptocurrencies due to regulatory concerns. In theory, by investing in mining stocks that own their mined bitcoin, investors get a way to profit from the mined currency at below-market cost, while having a real deal. At the same time, the shares of public miners are simple for these traditional investors to buy or sell. You don't need to create a fancy bitcoin wallet or open an account with an online exchange or specialist market writer; simply call your broker as usual.
