Get 10K in a crypto account. Start an NFT company, sell an NFT for 10K to your crypto account, the NFT is now worth 10K, as you paid that for it. Your net worth is now 20K. 10K in crypto and the NFT valued at 10K based on sales price. Now sell it for 12K to some idiot that believes it was worth 10K, or sell it for 1k at a great discount, and declare a 9K business loss as the asset is not worth the acquisition cost. Rinse and repeat with a new monkey picture and soon you are worth a eleventy billion dollars. Get some friends involved and you are all worth eleventy billion. Essentially modern check kite/tax fraud, with more upside sales potential as people write news articles about it and people think these things have value because someone on the internet said they do. If you do it with regulated financial products it is a crime, but governments have been slow to apply regulations to these things, so anything is possible.
