the real king is still bitcoin, bitcoin still the central of cryptocurrency even many altcoin is growup and get big support from their community
So that no one said, but as Bitcoin was the most popular cryptocurrency, it will remain for the next 5 years. I am sure about that. At the moment he has no competitors.
not only for the next 5 years but it can be at any time as long as the cryptocurrency is still there. bitcoin is the main coin here and the benchmark for all coin coins here and the highest price. it's not easy to compete with bitcoin because bitcoin has been popular since a long time ago.
