The profit taking strategy still needs to be revised. We can't sell everything at once. If the on chain transactions are hot, such as those with a transaction volume exceeding 100 million, at least 10% of the chips should be kept. Looking back at my bome operation, I bought for 17 million and sold the principal and profit at 42 million. All sold out at 190 million. I remember @ BTCDayu got on the bus in the range of 40 to 50 million yuan, and then said in the investment research group that it would rise a lot, but I didn't believe it. If you sell half of the 190 million yuan, then sell half again when you reach 500 million yuan, sell the remaining half when you reach 1 billion yuan, and sell the remaining half when you go on Binance. Estimate that the investment return will at least double.
