As an old investor, I want to give everyone a risk warning. The current contract positions have reached a historical high, and Bitcoin is approaching the psychological pressure point for most people. The probability of a sharp drop here is very high. Those who experienced the bull market of 2021 should understand. I will never forget that day on September 7, 2021, when Bitcoin dropped 10% in 15 minutes, causing a number of altcoins to plunge over 20% within just an hour, leading to my one million in profits from May 19, 2021, being wiped out overnight.
