because of th hard fork it is very unlikely that bitcoins will be replaced by any other cryptocurrency .this is not going to happen in the future run .well it may rise more than bitcoins but i think it will be for a few amount of time .i the last bitcoins will always rule the world.
Totally agree.Bitcoin is too strong to be replaced by any other cryptocurrency.Bitcoin already exists for some good years and I think it will have a very long life.Bitcoin is the king and I think if Bitcoin vanishes the other cryptocurrencies will disappear too,because there will be no more trust in cryptocurrencies.Anyway,I don't think Bitcoin will disappear,because has too many "followers".
