I started on pokerworld in late 2007, it was a very small American site, most people never heard of it, lost maybe 200 USD then i started play on pacific poker(AKA 888 poker), nl25 games were very soft, i deposited 50 USD and turned it to 1000 in maybe 15 days, i had bad luck one day, i decided to play some Blackjack game on that software, lost all the money in that account I started playing poker seriously on Everest Poker since July,2008, bought PT3 and even downloaded some coaching videos, i made like 1700USD in my first month by playing NL50, i was kinda bad but games were really easy, pretty much everyone today can beat those games. One day, i heard there was a thing called rake back, i was like "oh, if there was more money to be made then why not?" I started playing on Boss media network, the site i played on was Poker Heaven, it was in late August, 2008, i guess. I spent 2 years on Boss Media, i played from Nl50-Nl150 euro tables(back then 1euro=2TRY and i played at NL300 TRY table a lot), i started playing on pokerstars.fr in August, 2010, that site was a fish tank back then, i mean, boss media was easy, POKERSTARS.FR was even easier in 2010(especially for NL1000 games), i made like 10k my first month there(only played like 9k hands, played NL200, 400 and 1000, yeah, i had never even tried NL1000 before that, i took a shot and realised i could beat the game).
I think the earlier, the easier, i heard someone who could only play ABC poker, no bluffing, not even skilled made 20K USD a month in 2004, just crazy, i also know an old unemployed women who barely knew the poker rules made 6k USD a month by clearing the bonuses offered by the poker sites.. My golden age for poker wasnt even half sweet, but i still wish to have that again.
