IMO convincing Coinbase, Gemini & others to use SLP for their stablecoins - actually moving more value on Bitcoin Cash (even if it's fiat) - that's a better use-case for BCH
Look at us: BTC = high fees (clogged network), ETH = huge blockchain (1 TB+, clogged network), BCH = we're spamming shit tokens, we could take-over more of their real tx volume
