$BTC exceeded expectations. I didn't expect it to reach 61000 so soon. At that time, I just felt that it might reach 61000 at 8 o'clock, but I didn't expect it to be realized at 4 o'clock. In my opinion, the subsequent trend is likely to continue to kill the bulls, because there are too many people doing longs. A drop of 2000 cannot completely blow up the bulls, so there may be a spike. I personally feel that it is cost-effective to open a long position at the current price, but you cannot hold a heavy position or high leverage. Keep the bullets, wait for a good opportunity, and then make a lot of money.
