The only other crypto currency I can think of replacing the bitcoin is the Ethereum. Many bitcoiners are buying it.
well, ethereum getting a lot of attention of crypto currency users. and bitcoiners also. but I don't think it can replace bitcoin ever.
it may get a good place in market(already have quite good) but replacing bitcoin is not easy. bitcoin is the only and first crypto currency and it is un-replaceable now.
Bitcoin is still a new thing, it is still getting bigger, however bitcoin is a precursor of cryptocurrency.
That is the reason i think that we may see some other crypto getting bigger, because we will see new upgrades, solution coming in- and bitcoin will be just old-fashioned.
No. it is not true. bitcoin won't become old-fashioned man. aren't you seeing that bitcoin is getting accepted in new sites, big shopping sites and big products?
there is no other coin which getting that much attention.
