well im currently all in into bitcoin, i think bitcoin offers something truly unique. Also the fact that it has a limited supply gives some sort of transparency.
A lot of people is talking about some plot going on with all this block size issue, to destroy bitcoin. I think that if someone/something has the power to stop bitcoin, then they can stop whatever they want.
So although there's a lot of new stuff around, i'd definitely go mainly for bitcoin, or for bitcoin if there is only one pick.
