My own opinion is nothing can replace dollars ,i think bitcoin will still an alternative money or payment for us .just what i think . But will see what will happen in the future .but it is better for me that bitcoin will still be an alt money.
Yeah i agree with you, Bitcoin can't replace dollar for now. And i think bitcoin can go along together with dollar. So bitcoin no need replace dollar.
Yeah dollar is more powerful and bitcoin is on its way to become more powerful in future, but will only use that currency which they find it comfortable.
for bitcoin to replace dollar is a long way and it will take so much time but first bitcoin must be more populaire and continu to grow in price and be used over all internat.online store and other payment.
and then to be accept in business so in that time it will be ready to replace dollar.
it is very hard to reach that but maybe it will come in the futur.
