The point I'm driving at is that exchanges are now taking it upon themselves to foster the widespread adoption of crypto by educating and simplifying crypto and blockchain but this adoption we talk about won't happen overnight.
One wouldn’t deny the fact that many exchanges most especially the centralized ones have provided ease or educational materials to cryptocurrency learning. Even the platforms are most at times easy to use since they provide Demo to mostly newbies and it has grown the adoption rate.
Nonetheless as a bitcoin Maximalist, I feel like the way this centralized exchanges spread the adoption or cryptocurrency awareness they tend lean away privacy concerns of users since it comprises their own platform. CEX will gladly advise users that their funds are save with them which is entirely not true. And just like what OP has said one of the reason for cryptocurrency apathy by some people is because of the fear of hacks which are mostly common to saving funds on exchanges.
The easiest bitcoin adoption method which will be faster remains the government policies or regulations. It is not that people don’t want to join crypto but just that they want a clear go ahead from the government first
