Debating if I should invest more into bc or just stick to what I have.
First world problems.
Depends when you need the money. Long Term - Just look here:
http://coinmarketcap.com/Are we better then Namecoin? Yes. Nxt? Yes. Mastercoin? Yes. Dogecoin? Yes. Ripple? Yes. Peercoin? Yes. Litecoin? Yes. Bitcoin? I don't know, but at that point BC is $5 so that won't be a problem.

Namecoin isn't really crypto currency. It's a crypto DNS. I wouldn't add namecoin to competing currencies. It has it's own class.
Mastercoin/ripple, more like scamcoin.
Dogecoin. I sold doge for bc.
Peercoin, never made to 100 percent pos. Shouldve done it, now they're too late to the party. Peercoin is dying
