The piper is piping. Your crypto-currency response will be weighed

The piper in "the 51st highlanders bid farewell to sicily" is a piper whose seen stuff you can't believe, and can't wait to get on the boat and head somewhere else. Alas, to fight, but you can't have it both ways.
I notice you elided over the 'hedgerow in your bustle' moment. Probably wise. Like the south sea bubble, some things are just emphatically un-knowable. Who even knew there was a market for garden-decorated bottom pads?
There was a BTC-e fine of $110M in mid 2017 that also noted the problematic role of Dash and tumblers. It is hard to image Monero and Zcash are more tolerable to FinCEN.
The bubbles are a worry when 80+ yr olds start asking me about BTC when its price is on the National News each night here. That's a slightly different problem. Ensuring that both currencies and virtual-currencies comply with AML/KYC/CTF/Slavery regs should be at top of mind for most ethical people I'd hope.
