Every monetary investment is a gamble. Every time you trust someone you are taking a gamble. I would definitely gamble if I had 50 million dollars. I find it relieves stress. However, I'd probably gamble my money on supporting the pursuit of animal rights and technological singularity. But I would still play Poker, Dragon's Tale, EVE Online and Heroes of the Storm for fun. Like... Gambling is definitely stressful, but it's something repetitive and gratifying that I can do without drama from other people. Just me and random chance. That said - my betting limit would probably be $800 if I had 50 million dollars. Right now my betting limit is whatever I earn off of faucets. If I were to bet more than 0.0016% of my networth on something, it would either be for a good cause or for a positive EV (e.g. investments).
