I would like to note that it was after Charlie announced the sale of his coins, the protracted fall of the entire crypto-market is began . I don't think he truly regrets the sale, most likely Charlie is trying to make excuses for his actions. After all, the crypto-community has several claims to him.
First, he should not have publicly reported the sale. If we look at the developments he reported the sale on the following day after he sold his coins. And I watched a trade volumes, it was day as day. The market quietly digested his sale. But apparently Charlie was so pleased with the deal, that he decided to boast, otherwise I do not understand the other way. I think he could report for example a few months later.
Second, today he says he regrets that we are in the bear market. I can't believe him with all due respect. His Twitter account is considered to be one of the most reputable and it was he who announced the sale of his coins with the words that he expects a bear market. It was these words that frightened the community.
That is, in fact out that Charlie full of joy left the cryptocurrency and problems to the whole community. He shouldn't have done that. I think this is the reason for his regrets.
