Hi @Jezzo
There a spreadsheet managed by @alexs with some crowd sourced data about Monzo users:
This is unofficial data, not provided by Monzo, so please take it with grain of salt. Numbers we have are a bit spotty, so it’s difficult to reliably tell how many cards are sent/activated a day - but it’s sure a lot.
I know that waiting in the queue can be a pain, so… insider tip for you 
- there’s a thread with golden tickets on forums. Having a golden ticket allows you to skip the queue. Feel free to browse and maybe grab one?
