Well I see wider acceptance of altcoins as payment, I think people will get frustrated with bitcoins large transaction fees.
I also think that people will think it is too pricey to enter into, going for a smaller coin.
This is all my opinion though, knowing me, none of this will happen.
Yes you are right but only in that case if the policy of large transaction fees of bitcoin are hard and fast and that could not be changed in any condition.
The currency that you are preferring over bitcoin is the one that I do not have heard the name of it if it can provide transaction on lower price then I am sure that bitcoin will definitely revised it policy and provide better services in lower cost than that of the others.
