Now I’m thinking of using a limit sell and deleting my Binance account. Will that cause any problem? If the price hits $75, will it auto-sell, or will deleting the account cause issues? I’m seeking advice from experienced traders.
Placing a limit sell order of $75,000
BTC and deleting your binance account won't work the way you expect it the order will be cancelled at point of request for account closure, but the best thing to do is to place your order wait for it to be executed withdraw your money and then walk away.
Your experience with trading selling at wrong time and buying the at fomo is not so much different from the experiences of other cryptocurrency traders, most especially the newbies who still allow emotions to control their trading decisions without taking into account the volatility nature of cryptocurrency market.
