I think buying fast and selling fast is a good thing in the current situation, because prices are changing rapidly. you buy then sell take profit some percent exchange to USDT buy when low then resell,
the risk is that if you are late in selling you can lose.
Bitcoin trading requires a prime mentality and the right decision, buy at the right time and sell when profits have been obtained. Don't be greedy, because in bitcoin trading, greedy is the most dangerous personal enemy.
