1. Digibyte (This will definitely rise in it's worth, the devs are very talented)
This isn't about "devs" anymore. There are a number of working, globally-scalable cryptos built, tested and deployed. There are top-tier quality websites built and operational. This is about legitimising crypto currency and getting sovereign countries engaged. That requires top level connections and negotiating ability.
2. VPNCoin (Wallet with amazing features)
Ooh great. Another altcoin. I wonder what's so special about them? Are they "very talented"?
3. SnowBalls (Announced Pump in the next hours/days)
I cannot wait.
4. Ripple (Ripple is Ripple)
Yes. Note the distinct lack of hype and hysteria. Their
actions speak for themselves.
5. Nxt (good for longtime investments)
Certainly
not good for longtime investment. NXT is an interesting project that has done well. But nobody's going to buy in to it - it's 99% tech-focused and the organisation is run like a hippy commune.
My 2c. I hope nobody takes offence.
