You guys have insane taxes. It seem so easy to grab such a bit piece of a pie. Tax department just need to send you an "invoice" for the % of amount recieved from crypto related services (exchanges etc.). That literaly looks like a free money even if you will accept the fact that the bigest part of crypto transactions (mostly small ones) will dodge the taxation.
P.S. How are they tracking the tokens you recieve (to make you pay 45%)? To withdraw the token money you should exchange them to BTC / ETH anyway.
