Altcoins, even Bitcoin is not fully anonymous. Its semi-anonymous. And this is why if you control the gates and control the amounts of fiat currency swapped for cryptocurrencies you can track, from that point forward, the route the flow of value takes.
Make no mistake. Governments see cryptocurrencies as a coup détat against the international banking system. And if you own or trade cryptocurrencies, you are viewed from the establishments point of view as taking something that is not yours to take autonomous control of your wealth.
In 2018 cryptocurrency demand was choked. As Bitcoin supply overwhelmed demand, the price of Bitcoin and other cryptos fell while the big players were quietly accumulating a position.
So what exactly is your point now, because I dont fully understand what you are insinuating. Is it that satoshi lied to us and we should all be scared of government and dump our cryptocurrency usage and investment? Make it clear please. As far as I know, bitcoin is still the most decentralized cryptocurrency, and the fact you have control over your personal transactions within it does not mean it is not going to be fully anonymous to external body out there.
Bitcoin is fully anonymous, and that was the major idea behind its establishment by satoshi, one thing you need to know is that satoshi might have something against the government which I am sure of, and that is why he created such system, and would never make any mistake to leave a loop hold because he is too smart to do so.
And the state is vseravno your anonymity. Say, Russia is preparing a tough regulation bill. According to the latest news of the RBC tele-channel, this law was postponed to autumn. However, it is easy to make them give up cryptocurrency. The Russian law said about 15 years of the deprivation of freedom. And who needs such a cryptocurrency.
