I just spent 3 months in London, and it's crazy how Monzo seems to have taken the market. Almost everybody seems to be paying with a Monzo card, regardless of age. Asking around, I consistently heard that Monzo's competitors like Revolut are going to be a future case study in scaling before great product/market fit. I don't know how many people have Revolut accounts, but nobody seems to be using their cards in public…
Why do you say it's a bad product? I use Schwab as my main account and it works great for me.
