Very interesting. I’ve always been in favor of about 80 to 100 buy-ins (though I prefer more, LOL). In live cash games, they recommend 40+, and that’s about what I’d agree with (50).

I also think players should bear in mind that the “bank” holding the player’s money pays the site’s expenses and invests the rest of that money, so naturally they’ll encourage larger initial deposits. This is exactly what got Full Tilt into trouble, all that cash just sitting there waiting to be claimed (or reclaimed) by its owner((s). Any time regulators see large amounts of ready money with uncertain ownership it’s just too tempting a target, whether bad things are happening or not. At least in a Nevada or NJ casino, the house is supervised by the state gaming commission. Many casinos and other gambling houses have gone bust, but few of their customers ever lost money because the chips weren’t honored for cash. This is one of the reasons I won’t play for real money on line. I know people who lost money when Full Tilt was shut down (I wasn’t one of them, thankfully).
