As for my knowledge is concerned i will suggest that the future belongs to bitcoins because each day more people are getting interest in investing in bitcoins which in returns give them handsome amount as it is the only decentralized crypto so the world is trending towards it which seems like in near future the world will changed their digital transaction into bitcoins.
that is a fact that people are entering in the world of bitcoin regularly and i am sure that this trend will continue for a long time. because still a very little number of people have knowledge about bitcoin while majority of people still do not now anything about bitcoin. But now the the increasing introduction of bitcoin the bitcoin users are also increasing from time to time.
