if you are asking about power among other crypto currencies:
bitcoin was first cryptocurrency to come into play.being ahead or first move a lot of time has been spend on it by both users and developers on this currency.the other currencies have been introduced but replacing bitcoin is not easy because it would require a great change in technology and as well as it has to build same or better trust among users which already have been established by bitcoin about the security and transactions
It seems to me that for today Bitcoin is very well rooted in the financial system and also in the life of every person. As for power, I can not say anything, but I definitely want to say that people are exposed to the strong influence of the IZO money opportunities to earn.
