Charlie: Now if you want to buy and sell Bitcoin, you need to go to a trading platform to buy it, and then you have to go to withdraw (pick up the coin) into your wallet, it is not so easy to buy and sell Bitcoin, buy Bitcoin. If you're going to buy Apple stock, you're going to go to your brokerage account and you're going to buy it. If Bitcoin has an ETF, it's easy for anyone to buy it. Some big hedge funds, now they don't touch Bitcoin because it's too complicated, but if there's an ETF, they can easily add a bit of Bitcoin to their portfolio.
