No wonder mixers have developed a bad reputation. Even though they’re meant for privacy, illegal transactions like these overshadow their legitimate uses.
Some government and blockchain analysis company doesn't even care whether mixers (along with similar tools) have legitimate uses. Although FWIW that news also mention DEX, CEX and other services which speculated will be used by the hacker.
My biggest concern about this bybit hack is the inconvenience it will cause to those that have huge stack of coins especially ETH because most of them will likely get their funds frozen too when the intend to move it.
If that happens, it's further proof that blockchain analysis isn't as good or reliable as some people expect.
