... but we must remember that as good citizens we are taxpayers because it is for personal interests not personal interests.
what is the bolded part supposed to mean? were you trying to say "for public interests not personal interests"
It makes me wonder, are people really that ignorant to believe that you don't have to pay tax over crypto trading activities, or are they blindly assuming that because crypto is "anonymous" they can keep avoiding taxation.
they definitely thought that, they think they can avoid tax forever 
also because the government in my country hasn't regulate bitcoin yet,
people think (strongly believe) they don't have to pay tax on profit from any bitcoin related activities *facepalm*
most ignore the principle of self assessment tax and the notion what counts as income
