From what I have researched, cryptocurrency has an acceptance
issue due to some false claims.
The first one being is used for illegal activities. This is the most controversial
aspect because of the media, which have no knowledge of the system.
Illegal activities have and always will exist, doesn't matter the type of system
used for the exchange of goods and services.

So you actually presented the problem, talk about, it and tell us that this is not something that can be fixed, ever.
It is as you said: as long as something can be used by greedy people to conduct illegal profitable activities then there is no cure.
Do you really have some solution?
