Comedian Bill Maher, the host of "Real Time" on HBO, did a hilarious send-up on Bitcoin and cryptos and the people who buy/own them. It was a clarion call for action."The power being used right now to guess numbers and win imaginary prices is the same as all the electricity used to light all of New York State!""Almost all the people who tout Bitcoin, the millennials, the Gen Zers, the Silicon Valley types, are money-hungry opportunists and you're not allowed to pretend you care about the environment."Maher's clarion call could morph into a tipping point for environmental action against the cryptos.
