And I'd just managed to convince a quorum of my friends to move from WhatsApp to Signal. At this rate I'm going to be using Mixmaster remailers and talking to no-one again before the year is out. Remember Keybase ICO? I try not to.
There is a near zero-chance my friends and family would have done this without buy-in from their nerd contact. I sold it hard. And this same nerd has been talking about cryptocurrencies too, almost exclusively that they are at best tulip-craze scams, at worst just a way to bait drug dealers and law enforcement onto your device. Not to mention the hideous environmental impact (and you are about to talk about proof-of-stake, just ... don't.)
I can not stress enough how much I want this experiment to fail.
