Well... I got into Bitcoin very early, so it's been ALL good for me. My advice is: keep it simple. Don't carp for the hype. I stick with BTC because, (1) It is the one people look to for the value of other coins (2) It is well established and moves up and down on a fairly predictable pattern. You can build your holdings by buying the dips and selling some of it at the peaks. Just be sure that when you sell, you keep the $$ on hold for your next buying opportunity. The other newer alt coins are going to go through a shake out period and I think, unless you like to gamble, it's best to wait awhile to see which ones have legs. Just MHO.
