Chase to ban all crypto-related transactions

I don't oppose it on an emotional level, but there's not a single meaningful framework I can imagine that would "ban all of crypto" as-worded. You could go a long ways combating fraud by starting with credit card providers, but that has zero effect on the networks themselves. People can (will, and do) trade in cash, and the blockchain will usually operate unimpeded. Regulation on exchanges is the tip of the iceberg if you honestly intend to kill cryptocurrency in the West. I say all of this as someone who delights in the collapse of trashy decentralized money machines, but also as a pragmatist.
