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???
Nothing, Bitcoin is the center of all coins, and I don't think there are coins that can beat it.
Bitcoin is widely used in various transactions and this will last forever, and some of the top coins in the crypto market will only be underneath.
