In the beginning you start out small... buying only a few bits worth of Bitcoin, to just get the feel of it. There are so many scams out there and you not sure what wallet service provider or method is
safe to store your coins. You start asking questions and reading up on the subject and sorting the bad from the good, until you find your way through this minefield of information. The trading into other
Alt coins comes eventually as you realize that profits could be made, not just from Bitcoin.... but in the end, most of it comes back to Bitcoin again. {more merchants and people accept it}
