Today Morning, One Thing came in my mind. BTC is really an amazing concept not only for the rich people while the for poor also, because no one can control the price of btc. For example, at 2017 -2018 if you are invested in btc then right now you can collect a huge amount to use like in education , in health, in your family or your future plan.
This is not the best thing about bitcoin, what you illustrated here can be related to its appreciative qualities, that is Bitcoin can increase in price due to its limited supply in the market and the continue increase of demand by the market. But that is not what make Bitcoin unique, its the decentralization that does. The possibility of you transacting anonymously is what makes Bitcoin unique.
Until its invention nobody could transact without a third party like an escrow or bank been involved. Bitcoin made transacting faster and borderless become a thing.
