I have had multiple affluent friends who are absolutely non-tech non-geek ask me what are the hot coins. They're shoveling tens of thousands of dollars into Bitcoin, Ethereum, and Ripple based entirely on the fact that there's a run up happening. They have no understanding of what it is and the intention is sell to the greater fool after another 10x move.

Maybe it isn't a bubble, but it sure does walk like a duck and talk like a duck.
