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???
I don't think that any coin can replaced bitcoin, it is the top of all coin for past years. It is the first cryptocurrency to be invented. The value of bitcoin can be down but it would not be loss. It is impossible to beat the bitcoin.
