The technical aspects of bitcoin, and the lack of easy tools. I think this will all change tbh, but the truth is that we are constantly redirecting users outside of our app for a wallet, an then connecting it to Flash. It's great, but a new concept in Bitcoin with little compatible wallets. I think this will change soon, though. We will soon release our wallet, it will have amazing features and will be super simple, working both on mobile and on desktop, automatically, no hassle, full self-custody. It's gonna be a special one
