"The dark side of crypto - being abused by bad guys for bad intentions" - this topic is always hot, I have read everyone's opinion, and found that most of the time it is easy to accept that negative/dark side of crypto.
I never think that we need to accept any negative, we acknowledge their existence but need to fight to limit it to the maximum.
But when we find the solution to that problem of crypto, we put ourselves in the shoes of governments who feel that their power is threatened by crypto

As of now, we have not found a solution to this problem, and perhaps that is the biggest weakness exploited by the opponents of crypto. KYC on exchanges or platforms does not completely solve the problem, even is abused by hackers.
Perhaps we have to wait more time for advancements in legal technology to create the best solution, while ensuring anonymity and keeping crypto from being abused.
There are many people talking about CBDCs, but it's currencies controlled by governments, they're not 100% crypto.
