The US Gov hates cryptocurrency. In fact if you read recent laws (last 5 years) you'll find the language is vague + it can be construed that if you're a US citizen + you hold cryptocurrency, you may be in violation of law.

Better to simply stick with fiat currency produced by every government in the world.

Treat income management as a currency exchange proposition.

Whatever language you speak, just target selling whatever you're selling into a country that reverse correlates the highest to your currency.

So if you live in New Zealand + US currency is strong against the Kiwi, then sell product into the US.

This way you always win big, because some currency in some country will always be your best investment.
