Additionally in most cases I'd think the lottery odds would be lower than the cost of traditional laundering (smurfing, through crooked banks, using cash based businesses like taxis etc.) Especially if you have to pay people to buy tickets.
Except for when it does: there are a bunch of people who have repeatedly jackpotted state lotteries, they're usually described as 'reclusive mathematicians'. But that isn't what I'm talking about. I just checked the TX Lottery Commission's site and it looks like scratchoffs would run, worst case, a 30% return. I can't be bothered to calculate the upper bounds, but I'd expect it to be 40%-ish. That seems good to me, I especially like that you can skip the part where you have to drive out to some hotel to meet an undercover Secret Service agent pretending to be a Wells Fargo employee responding to your help wanted notice in Soldier of Fortune.
I would ask for monero and would not care if the FBI is the buyer. The most they can do is to watch exchanges where monero is exchanged versus dollars or other cryptocoins. Then do this a few times over and start buying goods with those then sell the goods on Amazon/eBay for hard $$$. Small amounts and even with 50 cents at a dollar is still worth it for one person.
