Edit: Either way, does not the law say that you mention that bad money expels good money? I do not understand your logic.
Gresham's Law:
Bad money tends to circulate, pushing good money into holding (aka storage).
And oh boy, are the BCash crew pushing it as a better form of spending, thus circulating money (ie. lower transaction fees).
Same with Litecoin. I remember when even Coblee was saying "Bitcoin is for holding, and Litecoin is for spending." He was basically shooting litecoin in the foot with such statements.
But let's be real for a second.
1. e-Commerce is rarely if ever happening with crypto. It just isn't. Even if the coin is supposedly "better or faster" for spending.
2. Traders want lower transaction fees for more trading and no fee friction. That's it.
3. Miners HATE hodlers, because they get no transaction fee revenue if coins just sit.
4. The establishment would love nothing better than HFT on-chain. But of course, they will never ever achieve such a thing.
