Keeping an eye on:

TenX (100 mil coins in circulation of 200 mil cap, more advanced than Monaco at the moment)

Monaco (9 mil coins of 30 mil cap, a bit behind TenX, but smaller amount of coins available)

AdEx (advertising)

NEO

WAVES

WingsDAO

XEL (Elastic)

XEM (NEM)

CVC (1 billion coins, to keep in mind)

OKCash (small volatile plays)

Breakout (small volatile plays)



For long term "holds" id pick Ethereum & DASH. Id stay way from LTC. Seems a bit dead in the water compared to the waves of Bitcoin that the other 2 react to all the time highs and lows come and go.

Mind you, these are just what im playing with this week/month. Its dynamic, as it should be. If you wanna hold long term, stick to the big boys and you cant go wrong imo.
