I was talking to my friend who is a very successful mortgage broker in Miami. Has her own company and made it through the market crises just fine with her business still in tact. Let's say you make a good amount of money trading coins, mining, and doing all the typical crypto stuff. How will you be able to show proof of income to a bank in order to get loans for a house?

Is crypto trading a legit form of income as of yet? I believe it is, yet I feel many main stream people still don't understand. I would like some help on how I would be able to explain this to someone in better term.

I am a beginner when it comes to BTC so please go easy on me if this seems like a dumb question.
