Statements like these are a great reason to buy more crypto. If tenured insiders are saying to steer clear, that's a buy signal for me. When they start to talk it up again, it's time to take some profits to load up the powder stores for the next round.
I see a few possible motivations for these recent attacks:
People like Gates and Buffet are making statements like this to scare off weak hands and drop prices so they can scoop up their stacks at low rates before things really explode
They're bitter because crypto and blockchain both have the potentially to fundamentally change their industries, and they're getting too old to welcome change.
They've been asked by powerful parties in the banking cartel to help the cause and scare the masses off of crypto.
Regardless, the more they attack it, the more I buy.
