The average person must have probably heard of bitcoin or cryptocurrency as an asset class, however the means to start and engage with it is always a problem. Many have been capacitated with knowledge and understands what the game is all about, but they have been stopped by a financial barrier that prevents them from reaching the other end of financial freedom.
There is no doubt in what you have said, people keep hearing of all this beautiful testimonies and yet some don't care, some care but do not have the resources and some have struggled to learn but can't. These are the dynamics of life. But, most times what deter people is the struggles involve in learning and so they look for what they deem easy.
But with time I believe a lot of persons will move into crypto because it is the future and a lot of person are seeing this and coming to that realization.
