While I do admire the pledge and I hope it succeeds, IMO, it's a bit too idealistic given how few people currently accept Monero. My suggestion is to have three tiers...platinum (the above)...gold (add "where possible" to each level) and bronze (add "or other crypto" but not fiat when not possible).
Thanks for your input - this pledge does not exclude people working with Fiat, it's more so that they keep Fiat with Fiat and Monero with Monero.
Not all businesses will be able to do that and that's ok, some will have to limit the number of clients they take this way but it's still a good step to get the Monero culture moving in that direction 😁
The pledge listed here is more a "word is my bond" social agreement to get folks thinking of a Monero to Monero economy, rather than a financial pledge or investment to me.
I don't have, nor do I plan to collect fiat subscriptions with Substack. At this point in time I'm using Substack more for convenience to test a concept. I'll invest capital into infrastructure if people find what Monero Master is doing helpful enough ☺
