Bitcoin is the first mover which gives it great advantage. There are many technicly bettr.
bitcoin wasn't the first cryptocurrency! there was one or two others before it.
and also there aren't any other crypto currencies that are better than bitcoin technically. you may find some interesting features here and there but they always have multiple flaws.
This is interesting information. Do you have the name of the digital currency that came before Bitcoin?
I imagine that even if these cryptocurrencies were useful for certain purposes, they probably did not have the same level of decentralization as Bitcoin, since they apparently did not reach the same level of success.
