There was no market that allows people or any users to buy stocks with cryptocurrencies. Even e-toro only allows users to buy stock shares with Fiat coins. Why? Stock Market and Crypto market is different. you cannot see a pair in stock market that is like GME/BTC or ETH/GME. Stock Market only revolves on money that can be withdrew in banks and be used physically. While crypto, as we all know, is just digital currency/asset. Therefore, no physical company can be taxed nor be allowed to operate if they use crypto as their main stock share currency as it is only digital and volatile.
