There are many cryptocurrencies out there, the fluctuation is wide and big. Theres a need of a coin that uses a process to stabilize its value.
No doubt that there is no other cryptocurrency or altcoin that can supersede the bitcoin. At least not for the next 5-10 years. Of course there are many rising competitors like Ethereum, ripple and litecoin.
Do you agree???
Right now BTC is the market champion and no any other coin has stamina to overcome BTC.However in future if some project comes out with something innovative technological edge over BTC,then certainly it would replace BTC but not now. ETH,NEO has the capability to do this.
