Well I want to take profits after this bull run. Imagine I invest 20k and it shoots to 100k. The 80k "profit" will be converted to fiat on the exchange, but it will be reinvested when I think the time is right. But under the current law in my country, I would have to pay more than 50% of taxes on this profit so that totally eats up the amount to reinvest. I can never expand my BTC portfolio when the government takes more than 50% of every withdrawal. That is not just a tax. That is legalised confiscation of assets.
