This clearly has nothing to do with the mixers. We should rather be concerned about how the hackers managed to pull such an hack. I have been following up with the story for a while now, and It still doesn't make any sense to me how a multi-signature cold wallet got hacked. That wallet I assume should even be safer than that of an average user who uses a standard wallet with a single private key. If such a trick could be pull off with a muti-sig, then what is the fate of those who uses a standard wallet?.
At the end of the day, the hack was probably to remind us that even those we entrust with our coin are not as perfect as we think.
It has everything to do with mixer in my opinion. The argument has always been centred on the legitimacy of the mixers and how they allow criminals to get away with stolen funds. I have no problem with them running their services whichever way they want but in an obvious case like this very one involving bybit, it's crystal clear that they genuinely support illegal funds to become legal using their platforms. Secondly, the issue of multi sig wallet being hacked is not longer surprising, this is not the first time it's happening. The same way we are improving our wallet security is the same way hackers are developing alternatives to breach the security protocols.
And finally, don't entrust your coins to anyone or entity. Always remember not your keys, not your coins.
