$BTC $ETH Divide the position into 10 points as I said before, and buy the bottom according to 1, 2, 4, and 3. Add once for each 10% drop. You can buy once at the current price. The extreme position of $BTC may pierce 49,000 (the bull-bear dividing line), but there is no need to panic excessively. Investment is to invest against the trend. Others are afraid, but I am greedy.
