I had previously doubted that Bitcoin would be replaced by another currency. But my mind has changed. Because I see there are many other cryptocurrencies that the developers are trying hard to solve the problems in cryptocurrencies. What about bitcoin? We don't know who are the developers and no effort is being made to develop it.
If you don't try hard, your rivals will win. Bitcoin's rivals will win too.
Replacing the bitcoin into another cryptocurrency,is not been happen for this moment or this several year ,because as my own prediction no one could replace bitcoin in the cryptomarket in value and popularazation,because bitcoin is the only one digital currency technology created by satoshi nakamoto thats is different from other crypto coins,it is the first initiated real cryptocurrency that cannot been replace or motivated by new altcoins,because mostly i observe that all altcoins value depends on the bitcoins price pump.
