Not the Dutch government: HODLing is taxed, selling only gets you questions from your bank.
Wow. Wtf. How does that work? You buy at 1k and it grows to 100k and you don't sell and you owe taxes on that 100k? What if next year it goes from 100k to 1k? Do you get your taxes back?
Seriously, don't sell yourself out to the government. Thats the very point of Bitcoin.
