It's my understanding that vests aren't taxable because they aren't tradable.
There is no market or market value for vests.
I'm in a bit of a unique situation, because I have A LOT of Hive and other cryptos that isn't income at all and will be applicable for long-term capital gains. The tax on long-term capital gains is 0% up to $40k a year... so I really don't have to pay taxes at all.
