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???
I highly doubt it but the chances are still possible. What makes bitcoin the reigning cryptocurrency to date is its market value and usage among most investors and individuals. Since bitcoin is also used as the main currency for transactions under the blockchain technology (which provides unparalleled amount of security and anonymity) people take advantage of these factors for future transactions among peers.
In my opinion there is no currency that can replace bitcoin, because bitcoin has a huge demand around the world, bitcoin is also the most popler coin, so to compete or even replace bitcoin is really difficult and time consuming
Let us be open to all possibilities in the future as it is unknown and bitcoin may be replaced by another cryptocurrency depending on the scale of damage happened to it. If countries would start prohibiting the usage of bitcoin then this may slowly become obsolete. Expect another cryptocurrency to arise from such circumstance that will cater to our goals and need for the future.
