Why is bitcoin so valuable?? my answer is very simple, because bitcoin is the king of all coins, so it is natural that the price is more expensive, bitcoin can also be said to be in limited supply,, the beginning of the emergence of bitcoin is indeed a lot of doubt, but over time, bitcoin grows and many hold bitcoin, After several years of bitcoin's presence, other coins automatically appeared, it can be said that if there is no bitcoin, maybe other coins don't exist either..
to be more precise bitcoin is the grandfather of other altcoins. bitcoin is older than other altcoins and the market is more plentiful and reliable.
From another concept, bitcoin is the figure that influences the movement of other altcoins.
so clearly bitcoin is very valuable and valuable than other altcoins, the measurement and determination of the market is determined by the price of bitcoin.
