This is utter BS. Crypto-currency to crypto-currency trading was always tax free and there is nothing special about this, as the same rules are applicable everywhere around the globe. If they make this taxable, then the crypto volumes may decline by more than 90% (at least in the United States). The GOP guys have gone crazy about crypto.
My take is, the bill is drafted by a stupid GOP person. I'm actually surprised no many crypto-land people/media picking up this piece of shit law.
