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.
Welcome to the EU, where the Euro is king and the taxes will forever be insane and will be paid by those with jobs to support the growing population which has no interest in getting jobs within their host nation due to the handouts provided due to a specific classification of political status.
The big thing for taxing cryptos mostly comes down to the observation of bank accounts, which isn't hard when a computer can make quick work of spotting outliers. Too much money too quickly? You're not declaring something, and that's what gets you in trouble.
