no one can stop people using bitcoin. bitcoin provide convenience to its users. bitcoin provides comfort and security. people will start leaving the current conventional transaction.
bitcoin took it's place very well and wining more people's heart and mind every day. bitcoin is very attractive because of it's price, security and lots of earning opportunities.. I think people wont stop using it although more people getting involved in it.
Yes people are really loving bitcoin with its features and how easy it is to use on some occasions like sending money its fast and has less fees.
They are going to stop with Bitcoin if they realize that they lost a lot of money with it or if they dont can make some profit with Bitcoin and that is really bad indeed.
But that is the bad thing, people that use Bitcoin must have some patience and that is really important to make some profit with it otherwise you cant make some profit.
