Forgive me if this is a stupid question, but I’m really not an expert on NEO.
Anyway, GAS is just the transaction payment for NEO contracts (similar to gas on eth), right? If that is the case I don’t know why you wouldn’t just buy NEO; but I have a feeling I’m not getting something.
As stated on the link above...rarity might send the value through the roof...assuming NEO is used more in the future as a platform. All the transaction will require GAS and it being too slow to generate may create an insane demand.
It is all speculation (as with everything in the cryptoworld)
