It is just my advice not to overlook these coins.
Most definitely. These three coins hold the most promise right now - NEM especially, not only due to it's dedicated, transparent dev team, but the features it offers and it's Proof of Importance nature, which will encourage spending and not hording.
I've watched NXT coin slowly increase in price over this last week or so. Whether or not this is due to the presence of NEM on the Asset Exchange i'm not sure. Either way it's pretty exciting. EXO coin is also one of those gems that goes by unnoticed - It won't take long before it gets noticed imo.
