When I play online then I prefer to be alone in my room without friends to concentrate and other reasons. In sports betting or regular casinos I love to go with my friends time to time because there is no fun and attraction being alone. The more you are the more excited it is to place bets on different things enjoying everything there.
actually always better to not gamble alone , as you will never in control everytime you lost , when you are gamble not alone there is someone who will always remind you to stop.
to concentrate are not a reason you gamble alone , usually those people have not much friend ?
