I think that Bitcoin will alway be above all other cryptocurrencies. Bitcoin is first cryptocurrency and that gives it a lot. It broke the ice and showed people what cryptocurrency could be or become. Also if it was not the best, it wouldn't have the highest price. Maybe in time it will lose to some other or new crypto, but for now its first.
Yes for now bitcoin is the unstoppable cryptocurrency among all cryptocurrencies. Many people is using bitcoin and a lot of people is now investing with bitcoin. The highest price of bitcoin is one proof that bitcoin is really the best.
As much as you can, just enjoy the every little piece of the profit that you can get in bitcoin or else you will regret it. As of now, yes it is the best among the cryptocurrencies because of the benefits and the opportunities that we can get in bitcoin but there will be a time that bitcoin will be over performed by another cryptocurrency which is better so as of now, let just enjoy the things that we can enjoy in bitcoin.
