Trading, speculation is risky and sometimes you need to accept a loss in your trade, but I have a way to minimize that loss. The first plan will be that you need to buy a lot of USDT to meet everyone's buying and selling needs, when there are people who need to buy your Bitcoin, you will buy it from the exchange and send it directly to their wallet; I recommend you to use Trust Wallet because dep or withdraw fees are very cheap. Therefore, you will receive a higher fee.
Absolutely do not buy and hold Bitcoin now because it will be risky, maybe its price will crash at any moment.
The second plan is that you only offer trading for USDT, XRP or LTC. All have very cheap withdraw or dep fees and very fast transactions, so it is both convenient for transferring coins and also receives a higher fee difference, and less risky when trading Bitcoin (because sometimes transaction fee is suddenly soaring).
