Millionaires are millionaires for a reason. Most of them know about money and look for ways to make their money multiply. Unfortunetly, I do know a few millionaires that do not consider Bitcoin and crypto in general to be a safe investment. They'd rather invest in gold and other "physical" assets and assets that can be liquidated easily. Once crypto gets a few more advancements, more people will jump on board. But there's still a traditional way of thinking for investments when it comes to big dogs. :/
