There are also other altcoins that has the same or even better than bitcoin but it just happen that Bitcoin takes the rank 1 and being the pioneer currency.
Now I pay more attention to bitcoin, because I really understand it well due to the fact that there is a lot of good information here, and due to the fact that the Amarkets broker offers a large number of instruments, including bitcoin.
