That is entirely possible...perhaps even likely... accordingly there are good arguments for and against. Focusing for the moment on arguments in favour, the photonic aspect appeals to me having been fascinated by photons and their relationship with matter for some time. It is this relationship between matter and light (analogously between the substance of matter (Fiat currencies) and the inchoate nature of light (Cryptocurrencies) that interests me. One may convert the one into the other by means of a relationship not entirely dissimilar to Einsteins wonderfully simplifying equation...E=MC2. It is this relationship between thing on the one hand (Fiat currency) and 'no thing' on the other (Cryptocurrency), matter and light, that bears comparison arising from their interchangeability. Cryptocurrencies create real substance, real value and remarkable utility even though they arise from the 'nothingness' of mathematical abstraction (ex nihilo totem fit - from nothing everything comes). Add the fact that the exceptional ideas underpinning Crypti orbit the seismically important idea of a currency that incentivises the movement and flow of the currency (just as photons have to keep trucking or end up with zero mass) and it may be that the word is a candidate alternative for micro-crypti. But your points are well made and better candidate names may be only moments away.
Edit: Samsmith16 pointed out the photonic resemblance, not I.
Quantum:
At the risk of thread drift, I must point out that you are 40 IQ points above most of the bloggers here.
Also, there was nothing wonderful about Einsteins equation E=MC2. The formula for computing the energy of a moving object was already old in the time of Caesar. Energy equals mass times the square of the velocity E=MV2.
All Einstein did was expand the velocity in the formula to the speed of light, and then propose, not prove, that such a mass then becomes pure energy.
Yes, I am a Mensa member.
Anyone bragging about being in Mensa is a total douche. Not envy either. Not to mention, the smartest guys I know (most of whom are likely in mensa) have probably never even given enough of a shit about it to mention it to me or anyone else we hang out with. Not much different than mentioning your SAT scores at a dinner party.
