Tax enforcement authorities from Australia, Canada, the Netherlands, the United Kingdom and the United States have have came together to form a Joint Chiefs of Global Tax Enforcement to tax the cryptocurrency. I think this will greatly decrease the prices of cryptos. What you suggest?
That is with the assumption of a lot of whales are evading taxes when it comes to their cryptocurrecy profit. But when it comes to a stricter enforcement and better transparency on citizens that are paying their taxes properly then I don't think it will give a big hit on the price of cryptocurrencies. Remember that some exchanges and wallets are providing transactions of their users to goverments now, so far I haven't seen any big cases regarding tax evasion. Whales might be playing it safe when it comes to their holdings.
