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.
Bitcoin today is increasing its price again back to 10k dollar so we can expect to earn more profit for those who are holding their coin for a very long time, so keep on holding till it reach 50k dollar just like what the speculations are telling.
