And just so its clear for those who don't read it, he's talking about taxing crypto mining (as ongoing income). He's not talking about tax on receipt of crypto as payment or taxing capital gains on crypto trades.
Well, that's a tricky one. It's certainly not earned income in a conventional sense, but it's probably unearned income, which is still taxable. I wonder what the reporting thresholds are and whether you just combine it with the rest of your ordinary income. The thing is, if it's a currency, then it's not taxable when you sell it. If it's an asset, then tax it when it's sold. It shouldn't be taxed on both ends though. That would be double taxation of the same asset.
I'm not a tax accountant or tax attorney though, so...:shrug:
