Of course this is not an easy matter to explain bitcoin to big people where currently bitcoin gets a lot of opposition from various circles so it is very difficult to explain to these big people how bitcoin actually performs, especially at this time bitcoin has not received adoption from various countries then this can be a barrier factor for bitcoin being introduced to big people or influential people around them, but if bitcoin has been widely introduced the process of adopting only then it is not impossible that anyone wants to be in the crypto world in the long term
Sooner or later it will happen, I believe bitcoin will make it happen. Indeed, one of the factors that hinders bitcoin is that there are still many who reject and prohibit bitcoin. Yes, there is no denying that it affects people who have big names. I don't think they really reject it, it's just that they haven't found a more detailed explanation that they like.
