Bitcoin as far as I know is the mother of all altcoins. It is a virtual currency where we can used it as payment online and can be use as an aaset and savings too Which is very safe compare to any bank.
Yes, I strongly agree with your opinion, currently bitcoin occupies the peak of altcoin because it has a different value with altcoin, I think no one can compete, many who already use bitcoin because it is said to be a savings asset or investment or trade, Bitcoin also ensures security For all its users wherever they are, and bitcoin is independent, so far many people have used and trusted it, I think bitcoin will be in place for a long time.
If you look at some facts about the good progress of bitcoin from the rising bitcoin population as well as the contribution of investors that help improve reputation and popularity of bitcoin, even some countries have declared legality of bitcoin as a digital currency whose function is equivalent to real currency.
