I would not lie about it. Simply be honest, if it’s a good loan the underwriter will not care (prob just curious as to how much crypto you are holding). This is typically an issue if you are in sales, etc and you don’t have years of documented (W-2, 1099, etc) income. If you are “borderline” getting approved, they may look at it as a negative. As long as your income is sufficient for the amounts you are betting, they will not hold that against you. That being said, we are living in a “different” world right now, this is simply my opinion (I’ve been in residential real estate for over 25 yrs)! Good Luck, hope it all works out well
