The reason $BTC may be related to the downfall of the Prince Group. The US and China have teamed up, with the US using technical means to seize the main Bitcoin held by the Prince Group, while China directly physically apprehended the company's founder, Chen Zhi. The news that the US confiscated $15 billion worth of Bitcoin from the Prince Group came out in October last year. Since then, various cryptocurrencies have been declining steadily, while gold and silver have accelerated in their upward trend. Dark web bosses may have also realized that although, in theory, cryptocurrencies are unbreakable through encryption, the individuals holding these coins can be physically compromised, and the information involved in transactions can be technically cracked. More importantly, since your goal is to keep this coin unregulated in the dark web, you naturally cannot obtain protection either. Regulation and protection are two sides of the same coin; once someone uses various methods to take it away, you have nowhere to complain.
