I think nothing happened between Buffett and Gates. They do not care much about the Cryptocurrency and Bitcoin markets. Therefore, their statements are personal and do not harm anyone. And these two men have relatively similar views about investing, that is, do not invest when the two investors have a close friend relationship. Simply so.
I think your post is funny. I mean, in a good way. I never thought that there is a rule in investing that said we should not invest when there are two investors that are friendly to each other.
Nevertheless, I do think their words still matters, at least to some people which in turn could change their sentiment about Bitcoin and cryptocurrency in general. But with the widespread adoption of the blockchain, I think crypto will become mainstream later on, that their words won't matter anymore.
