There are many cryptocurrencies out there, the fluctuation is wide and big. There’s 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???
According to this article: Quora
https://www.quora.com/Which-altcoin-will-replace-BitcoinNone. There are new technologies, that will have their niche. Each crypto does a different thing, but Bitcoin is the most tested, the longest, and everything in crypto goes through Bitcoin.
Bitcoin will drop as market share in time, as many other flourish, but will remain the leader of the pack, even though it will increase less than others.
So if there is one to replace Bitcoin I think it is Ethereum long term, but there are many contenders. Also Ethereum is a different thing actually. They are all called “coins” but Ethereum is a network, with many real world uses.
