If I invested 30k in Ethereum and when my investment goes up to 60k, and I sell 30k just to get my initial investment back, will I be taxed on that? I live in the United States and just bought Ethereum this year.
No, because there are no tax rules for that, and recently I read that if a YouTube user has a special income, he will be taxed if the user lives outside the Americas, now that's not the case for crypto.
