Since January 1st this year, the BTC market price has only experienced two consecutive declines for more than three consecutive days. According to the halving trend in previous years, with about 10 days left, it is better to short at a range of 3%-5%. Instead of buying all at once, it is better to buy short at a range of 3%-5% every time it rises.
