People need to have somewhat obligatory law enforcements to move to decentralized exchanges. They need to have reasons to spend their decent time to learn and practice using decentralized exchanges.
...
These are common lack of knowledge.
Why and how did you conclude that it was worth a decent amount of your time to learn about these issues on the forum?
I learned a lot here, technically and it is why.
Do you mean that they need to be prosecuted or otherwise harmed, before they have a reason to move from the exchanges you listed?
Is being scammed or knowing they can be scammed as others have been, not enough reasons to look for a safer way?
Why did you learn all you know about it here, if you also had no reason to learn it, and could have just ignored it as they do?
