Because of quantum computers threat to bitcoin security.
I was thinking, he has been thinking about this before, but the recent Coldcard issue would have been what that initiated him to finally make up his mind.
But many people are buying the dip instead.
I think he makes a wrong decision. But it is his bitcoin, he can do whatever he likes to it.
I did not know when he bought bitcoin, why publicly announced that he is selling.
Bitcoin all time high in few year to come.
Why do we have care about Jim Cramer?
In many years, he talked many things, many times about Bitcoin and the market but his sayings are like reversal indicator in the market. If he says something bullish about Bitcoin, the market will be dumped days after that. If he says something bearish about Bitcoin, the market will recover, short squeeze, bottom out, start a bull run.
I don't know about this time and I am not sure that it is a bear market's bottom signal but without him, his saying and his selling (if he actually sells his coins), I know that there are many good months ahead for accumulating more bitcoin.
