People must declare their income from cryptos, but they like to be in gray area. Many many people has generated massive taxable events as they moved their cryptocoins into other cryptocoins as a means of diversification, for example. They just like to think of it as an "invisible" event that's not government's business.

But then, the same people complain about quality of public education, or why 101 sucks, or something along those lines that require tax money.

Currently, cryptocoins are seen as "have your cake and eat it too".
