Of course they want, but only how they will do it. States want to tax everyone who makes money on the Internet but just dont know how to do it.
There is a version that the creation of bitcoin and subsequent altcoins was under the control of certain services of certain states. This is a bit of a test. Thus, they are well aware of how to receive taxes from those who make money online.
If this were so, then I think they would have long taxed everything since the annual turnover of funds on the Internet is very impressive, this is a huge amount of money.
