I don't think that bitcoin will ever be replaced by another crypto currency. Bitcoin is the original and the true cryptocurrency, without bitcoin there will be no altcoins. Altcoins will stay alts, I mean alternate crypto for bitcoin to have a profit, but they will never leave bitcoin or replae it. They are just using altcoins, so that they can have a profit from it, but when the time comes, thwy will be converting it to bitcoins.
Being the original does not justify that it will prevail and nothing will surpass it. Take note that an old one can be replaced any time by a new one, especially when the new one is better that the old one. So being the original is worthless if it will not improve itself to provide better service.
the past is telling us what it will happen in the future.
there few very good (at that moment) e-currencies like e-gold or liberty reserve. they are down now...
bitcoin is just another one. it's trendy and nothing more. if you are honest with yourself, you will see that it has nothing better than any other e-currency but contrary. it has many bad things like a huge time for confirmation. there will not be a mass adoption for Bitcoin because it's fluctuating without any sense. the big exchangers and the miners are manipulating the market as they want.
the shit with
demand and offer is just for kids or brainwashed people
BTC is an opportunity to make quick money and then go out.
This justify that being the original has nothing to do with how long it will prevail. The future is very unpredictable.
