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???
Yes. Actually, Bitcoin is the original of the species of cryptocurrency. But it will reach its limit sooner or later. It has to. And as crypto currency is definitely the future of currency, what then? I suppose we're trying to predict the successor of Bitcoin here. Newer coins have been created which don't contain the faults which Bitcoin, as the originator, had. For want of a better word. So as you say, there are a few likely successors to Bitcoin's throne. That successor could be Ripple, Ethereum or Litecoin. The only problem is, it's tough to predict a winner. It could even be something other than the three just mentioned. So the only thing to do, my friend, is wait and watch. In my humble opinion.
