I try to use my intuition when it comes to coins adding value thru a product or service that will stick. I feel coins being adopted by large corporations to be a safer bet. I guess eos, iota, neo, steem sound legit, but who knows.

Yeah, that's a good rule of thumb as long as you remember that big corporations were not enthused by crypto in the first place, so sometimes we as a community need to support the right stuff to give it the best chance, way before it becomes "good enough" for the big guys. It all starts with us - the "simple people" :)
Just like Bitcoin, Steemit, EOS etc.
