I think the biggest problem of bitcoin is the concept of this system is hard to understand that's why many people misunderstood of what bitcoin can do and this the reason that until now it is being banned in some countries because they doesn't have enough knowledge to realize bitclin system are good for our future.
Bitcoin's basics are very easy to understand, so that's definitely not a problem. If you for example go in depth and focus on how transactions are set up technically, then things are obviously different, but that's not something the mass thinks about or is remotely interested in. Once you understand the basics, and you demand more advanced usage, you'll educate yourself on that, which is how things work. No one forces the newer users to understand everything related to Bitcoin -- most people still don't even understand the internet, and that while it has been available for more than 2 decades. It also comes down to your personal will to learn something. If you aren't willing to invest even a few minutes of your time in understanding Bitcoin, you are just limiting yourself.
