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, there a lot of competitors, but I think Lightning will help to overcome all the disadvantages of bitcoin (low speed, high transaction fees) and preserve its first place.
As you said, at least not for the several next years.
At the same time, there are projects that offer a principally new way of arrangement of blockchain (additional layers that can theoretically allow up to a million of transactions per second), so we should keep an eye on this new technology.
Bitcoin is a coin that very able to be relied upon. because with the development that is present in Bitcoin experiencing a growing development so as to generate substantial profits for future. this does not close the possibility for other coins Cryptocurrency to continue to increase and replace Bitcoin in the future.
