My observations are that way. I think Bitcoin needs to reach larger quantities. Can use bitcoin in people who are not interested in technology?
Can people use the bitcoin in the profession group like tradesmen, teachers, housewives, firemen, butchers? Are we going to see the days that these people use bitcoin?
Here iny opinion about 10-15 years after everyone will use Bitcoin as a payment for small small buy and sell of the things .
Because currently the many people have the habbit of use fiat only because they have ease to use and also there are not much restrictions of fee for transaction because few private companies serving the services of wallet for the fiat where everyone can make send and receive fiat money without fee from wallet to wallet .
So I think that will take some.more time to leave traditional types of the payment and accept Bitcoin .
But also the confirmation system generating the big problems in Bitcoin transaction .
