@paulanthony. IOTA has a great platform of Tangled right now. Its quite an innovative concept to say. But IOTA overall depends on IOT devices for its success. Basically, one cutting edge technology relying on the growth of another cutting edge technology. The way I see it, first IoT needs to go mainstream for adoption. This is atleast 3 years away. Post that or in parallel, Distributed systems will need to get adopted. To me this seems a bit longer on the horizon.
In terms of Quantum, not yet mainstream. While its a great area to invest from a hardware perspective from ICO or actual usage perspective, its further away than IoT, but coming for sure. Both the above technologies will grow for sure, but will IOTA or QRL or QTUM be there / sustain to take the benefits, is questionable.
RE: In the future... ICOs will run on EOS!
