Is it even possible to buy into any games with .04? I like the donate it to Daniel Negreanu suggestion. At least give him a funny WTF moment to spice things up a bit.
Every month just transfer him like some small amount of money, and if he ever gets back to you just tell him that it's because he's your favorite poker player and your inspiration and this is your way of saying thank you. Then tell him that you'll promise to transfer more in the future as you become more successful.
