Among the crypto currency Bitcoin is always more powerful than any other alt coins in the market because it is the first crypto currency introduced in to the market on 2009 and after that only the alt coins are arrived in the market.
yes that is right and bitcoin has already have a good control over the crypto market, and i think a lot of reasons are there for that, but i think that he major reason is that bitcoin is first crypto currency created, and still people are taking interest in bitcoin.
