Binary decisions are poor. Diversify.
60% BTSX, 30% NXT and 10% Peercoin and you're probably guaranteed to either be filthy rich or break even.
BTSX has largest chance of success by far. NXT is doing a lot of things. It seems NXT's limited distribution may not hurt them that much and it helps them finance projects. Peercoin has a chance of sticking around with their self-funding too, so I wouldn't count them out completely. BTSX has the most going. NXT seems to have started to follow their lead with NXT's recent announcement of direction. (The corporation metaphor)
I like NXT, although I've had my discomfort with the closed forging concept. I'm getting into Bitshares, just need an idea or some product/action I could do to get people to vote for me. I might consider using some of the garnered BTSX ( if I ever do get any after IF I become a delegate
) to buy some NXT again.
