If I have the fund to purchase a house, there is really no point of getting a mortgage. The funds I made comes from Forex trading. Forex is a legit global market and I am sure the banks and IRS knows what Forex is. And I do not need to further explain what is Forex exchange market. I just need to show proof my funds came from my Forex trading brokerage account. I withdraw most of my funds from my Forex broker account to Coinbase bitcoin wallet so that I spend it right away without involving the bank. Now, I just need to find a safe way for the banks to accept my funds from Coinbase or find a house seller that will accept bitcoin as a payment.
