I even tried to build a complex, API-based payment network for it. It didn't work. Finally, accepted Bitcoin's limitations as "p2p e-cash".
Then met Vitalik/Anthony/EF.
Jumped back in when I realized zero-fee, in-app, API-based, and censorship resistant payments still was a problem needing a solution.
HQ-to-Location chat for franchise and chain stores.
Saw two things:

2) The ~4% fee that locations pay HQ as part of the franchise agreement could be a smart contract
Studied the Ethereum dApp ecosystem. Realized that "gas" was an economic primitive for gamified banks -- not a world computer.
Bitcoin was on its way to becoming joule-backed digital gold.
Still didn't buy into new money being created on top of new, speculative money.
And there were no plausible zero-fee models for the merchant (or app developer).
Along the way, we spun out @storecoin as a new blockchain for franchise _ chain stores.
We were building zero-fee, p2p, highly programmable payments infrastructure for the centralized internet (apps not dApps).
