Taxes seem to be unfair to majority of population especially in countries where politicians are very corrupt. But , if everyone decides to avoid taxes, the economy will come to a standstill.
Well, we can't avoid some taxes... but if we can skip some of them why not?! It certainly depends on where we live, some countries are just very corrupt as you say, and I live in one. There is a gray area where many things are unregulated, and if I can avoid some taxes I will for sure. I don't think that gambling with crypto is taxed at all, but what is taxed is cashing out through the banks... but I don't care about that, my cashouts were p2p, so somehow I am still anonymous.
Crypto is far better than fiat, simply we don't have to bother with some procedures and third-party services... Direct & instant/ fast deposits/withdrawals from the wallet and low fees are what make crypto better.
