A great team and a great vision.  While other altcoins get pumped and dumped for speculation, the real solid projects will sustain and come out on top.  The way I've been thinking about it is like the internet boom.  Google, Yahoo, IBM, Microsoft, Apple, AOL, etc.. were all the solid projects coming out of that era, while others were speculative.. they came out on top.  Think BTC, LTC, ETH, ARK, DASH, ZEC.. although maybe not as sexy anymore for day trading because the insane initial gains aren't there, they will be in 1-3-5-10 years while other coins and projects die off.
