What if some country decides to pay pension to working population in bitcoin ? What percent of people will agree to getting pension in bitcoin in your opinion ? What will be the benefits and limitations of this occurrence in long term on people and economy ?
It would be great for those who have known and understand bitcoin well because they can use it as a currency and as an investment tool while keeping the high security of their coins. But I don't think this will be easy for those who don't have even idea about bitcoin that its existing and that it can be use as a currency like fiat, and for sure assuring the security of their coins might be very hard for them and they might only put their coins into danger.
Since we are talking about retired people here, then I must say that majority of them are not excellent enough when it comes to being knowledgeable about bitcoin. Although it can be learned but I think teaching these pensioners requires a lot of time and patience before they can get the real idea of bitcoin and how they can use it on their own advantage.
