I'm not sure I agree on either point. For the price being determined by usage, I think this is somewhat true, but only a sliver of the full picture. I'm not sure why this has become such a meme for FCT. No other crypto, BTC included, is measured to such an extent by its actual usage. Per market cap, FCT may very well have the highest usage-to-market-cap ratio in crypto already. Look at the 13 coins with a larger market cap here:

Which ones have higher actual (non-trading) usage than FCT at the moment? This alone is pretty amazing IMO. And this is setting aside the very real reasons for a speculative premium (Gates, Draper, DHS, SMARTRAC, etc).
I also disagree that M3 will be the trigger. Paul Snow called M2 "the capstone of this year and many others." Relative to M2, M3 is a more minor milestone (though obv extremely important in its own right).
