There is some rich irony in calling out the lazy old people sitting on fiat when easily 99.9% of "cryptocurrency people" are sitting around HODLing while they wait for their COINZ to MOON. If contribution is your value argument, at least make a modicum of effort to list some of the great open source work contributed by the cryptocurrency people. It seems that most of the "work" is either minimum effort ICO garbage meant to enrich the principals or is blockchain-for-the-sake-of-blockchain to get a marketing boost off the hype.
