The problem I have tearing crypto apart is that I don’t really understand it technically at all detailed level. My objections are all philosophical. It uses up a ton of energy so people can speculate and do arbitrage. How is that worth it? I’ve used it to pay journalists in Afghanistan and appreciate that but I’d rather all this energy be spent ending sanctions. What am I missing?

Be prepared to discover a lot on the philosophical part of blockchains. 
My mind hasn't been blown like this since the beginnings of the internet 😅
