Do you think Ether will catch up? The technology is more advanced, but will scalability of ethereum be an issue?
No I don't think that ethereum is gonna catch up with bitcoin, I know that it have a better technology and also faster time for transfer of funds but that doesn't mean that it can surpass bitcoin that easily, it's the most backed cryptocurrency, and also the first ever cryptocurrency to be made.
And also that bitcoin is also evolving with time with major network implementations and changes to combat the problems that it is facing now.
I agree that ethereum could not cope up with what bitcoin has gone through specially the progress of it value in the market right now. Possibly bitcoin will hit that very high price within five years also with ethereum but still its second to bitcoin, because of the demand still couldn't surpass due to ethereum has to be traded first to bitcoin so it's still depe dent with btc' economy. However if agreed on some exchangers sites in the future maybe there will be an implementation of ethereum to fiat trading, then we can say the possibility is there already.
