There are newer cryptocurrencies than BTC with better technology. However we often insist that BTC is "king" because of its "first mover advantage" and its greater adaption. But then USD has far far greater adaption than BTC.
Shouldn't we value more technology than adaption? Isn't it natural that in the end other cryptocurrencies with better technology will prevail?
Bitcoin will always be the king of all cryptocurrencies, some other cryptocurrencies are just relying with bitcoin, if bitcoin drops then altcoins will also drop just like bitcoin and if bitcoin recover, altcoins will also recover its price. It is always happening and I think that is the truth.
