Re: Will Bitcoin be replaced by another cryptocurrency?
Yes it could happen but i doubt very much it will happen the short to medium term, to actually make bitcoin obsolete would be a achievement.
It would have to offer something very important for mass adoption which Bitcoin doesn't offer.
And that something would need viral uptake.
I am planning to make that Bitcoin killer.
And yes very difficult to achieve and implementation is a Herculian undertaking that is more likely to not be achieved quickly enough.
Although Bitcoin can copy any innovation...
Bitcoin can't copy every innovation, especially if that innovation turns all the existing mining farms into useless door stops. The vested interests in Bitcoin could never agree to copy radical block chain overhaul. Also that new design would already have the first mover advantage with millions more users than Bitcoin. Bitcoin can't scale so it won't have those millions of users to start with.
...yes it could but at this rate of popularity its going to be pretty hard for some other crypto to take over...
What popularity? Do you have any clue that Bitcoin has less users than any one of dozens of minority marketshare social networks.
Virtually no one uses Bitcoin for commerce. The main use of Bitcoin is for avoiding capital controls, speculation, gambling, and "nefarious" activities. Bitcoin isn't close to becoming mainstream.
Merchants accept Bitcoin not because they get a lot of sales from it, but because it is free geek-cool promotion to the geek demographic.
