And easily mitigated by converting the amount you owe in tax at the time your are paid. I don't see how this would be different than getting paid in any other currency. The problem in your scenario is not really to do with tax, it's that one has effectively expended $10,000 worth of effort for $100. If someone was worried about this, they shouldn't be accepting BTC as payment, or they should convert it to fiat currency immediately upon receipt.
