I'm gonna be straight with you: it's an interesting thought experiment if you ignore the entirety of the history of the industrialized world. If you
don't ignore it, it's not even novel.
ICOs are valueless trash in ninety-nine-point-nine-nine percent of all cases. This will only change, maybe-if-you're-lucky, if they are securitized and regulated, at which point it's the new "oh but stock!", and it's still not going to be a sane deal for a worker because the worker has no real way to deal with either counterparty risk of exchanges (meanwhile, dollars involve no such risk) short of paying a vig--you know, like how companies pay poor employees on debit cards with fees, how's that reality sound for everybody?--or safety of exchange rate, because LOL your company has a bad quarter and now you can't pay your rent because FacebookForCatsCoin no longer makes the speculators, the only people who are paying attention to it, sufficiently money-horny.
Sprinkling crypto on company scrip doesn't make it anything other than company scrip. And it's a bad idea for companies, too, because a mere, what, ninety-nine percent of companies have no public stock and would very much like to keep it that way?
