First deposit was $150....20+ years ago on
pokerstars. Went busted once doing a challenge 15+ years and had to deposit another $50. Since then on my main site Pokerstars no more deposits.
Over the years I've invested $50 on each of the following sites just to try them out: UB, Party
party poker, Full-tilt,
888, Blackchip and GG Poker. Don't think I'm missing any sites but feels like I'm missing 1-2 sites thou.
^So all-in total that's $550 over 20+ years. <-----That's not counting many many many books, a couple courses and PT4. <----Adding all those to the $550 likely closer to $1500 totally invested. All them/my expenses were covered by poker winnings. So in the end I invested ZERO and made a good profit and still counting.
Most expensive buy-in online the Sunday Million for $215 a number of times over the years. Live buy-in $330 at my local casino. Again all paid for with poker winnings.
Cheers!!!
