I don't know why people want to hide themselves from the eye of governments,if they are everything legally and obtained the money in right way then no need to worry about and also you have to pay the right taxes from the earnings or it also will be a punishble offence.
But lot of loopholes and underworld market available where we can pay extra and can get everything done in the way want.
It's not about paying the taxes all the time. You can't believe how a govt can interfere in all of your funds, it depends on the country where you live though.
Good point,but when we earned all this money in right way then they can't take our money from us and if you still thinks that they will take your money then better keep it as cryptos in the way they can never take anything from us without our permission and for sure we can use cryptos for paying many things even now and in some years it will be everywhere so there will be no need of conversion.
