Good morning everyone, in my opinion there is no better site to start with, this depends on each player, I believe that the ideal is to play on several different sites, if you are starting out the ideal is to play Mtts with lower entry fees to get up to speed with the software and the game.
I play on several different sites, the site that, for my style of play, is most difficult for me to profit from is Black chip poker.
Sites that make the most profit are pokerstars, GG poker and 888poker, and GGpoker, which was a site that had difficulties making a profit, is the site where I have the easiest time, see how important it is to play on different sites.
