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???
Bitcoin is the mother of all coins and I don't think any coin will replace it, it is widely used in different transactions and I think bitcoin will be forever the top coin in the market some are just next to it, but bitcoin is and forever will be on the top.
