I immediately quit my "job" gambling for a living, pay off my parents' home and pay their property taxes, and spare no expense in repairing my health to absolute optimum level like a San Francisco billionaire. Quietly move far away from home into a humble but safe area, and pretend I'm still working so nobody ever asks me for money. Nobody but some of my immediate family would have any idea that I'm now worth over 300,000,000 dollars.
Once my family and I are situated, take some of the money into the casino and play some ridiculously huge bet on a slot machine until a massive jackpot occurs (don't come at me about this, I literally play slot machines for a living and have years of data about how they behave, and I do know this would be a net loss). A 300 dollar bet on a progressive machine will eventually hit a 1000x bonus at some point during the chase if taken from the bottom, as well as several 100-200x bonusese. Even though this will certainly lose a few hundred units, it will give me an explainable 500k or so I can take pictures of, while not photographing the net loss between jackpots. That is enough that everyone in my life who doesn't know about my actual wealth will have an explanation as to why I'm suddenly a property owner, and they will never come asking for money.
Once I've got my wealth and paid my one time tax in the casino to keep peoples' suspicions at bay, I buy an El Salvador citizenship and property, just in case things really go south in America and the hordes and their political party come for racial vengeance with renewed bloodthirst. Relocate a large portion of my assets there so they aren't under the sovereign control of the IRS, just in case.
Easily find the wife of my dreams, since I'm no longer merely handsome and White, but also able to display a little bit of wealth. Never ever inform her of the true scale of my wealth. Put all assets in a trust that pays out to my kids when I die.
