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.
No. Bitcoin is not anonymous, it is true, but some other coins are anonymous.
In Monero, you cannot see where the coin goes. Even you cannot see a single address balance without keys.
For example, if you buy bitcoin and use it to buy Monero, then withdraw your Monero, then send again to other address, you will completely become untraceable.
