we setup a multi sig electrum wallet so we can manage funds together

all our internal processes are non custodial

we train devs in BTC. It's a mission. We also work with lots of businesses that are working on this too. Advice: make it super simple.

process: Years of practice

I suggest a website or app that handles both BTC and flat.

I have a bookkeeper that is great. Not sure if I trained him in BTC or he trained me 🙂
