yes you are right I really agree with you, this bitcoin seems more suitable if used for investment because bitcoin has a very limited price so surely the price will be very expensive and can provide benefits for those who have bitcoin.
Satoshi Nakamoto may feel that he failed in making bitcoin as the crypto for online payment, but it's satisfying in a way how bitcoin turned to be an investment where it changes the lives of others who believe in it.
I believe that too but I think Bitcoin is a great investment option than some because it allow anyone to invest in any level because if you invest in property or share market you should have a considerable amount of money in the beginning and even to start a good business at first the initial cost would be much higher but in Bitcoin it allows to invest according to the investors financial level.
