There was a time that as long as you have a way of depositing into a betting site you could deposit as much as you wanted, when you wanted and could place a bet of any value too.
However, there are of course some people who do experience problems when gambling and may not be able to control the amounts they spend hen gambling too, and that is why recently some serious consideration has been given to player betting and gambling limits by all leading gambling commissions.
As such what you are going to find nowadays is that when you sign up to a sportsbook and then log into your account, each time you do so you will be asked to set your own personal betting and gambling limits, that will allow you to be in control of your spending at that betting site.
You are always going to be best advised to make use of those gambling limit settings, for that way you can plan in advance just how much you are prepared to lose, and you will also be able to determine just how long you will be allowed to stay on that site and bet for too.
If you do find that you would like to stop betting and give up completely then there is another way that you are going to be able to do just that, if you feel you lack the willpower to give up gambling on your own, and that is by you requesting to be self excluded from one or more betting sites.
A self exclusion is a way for you to ban yourself from any betting or gambling related websites, and once you have filled in the required forms then at no time in the future are you going to be permitted to gamble at the sites that you have self excluded yourself from.
All licensed and regulated betting sites are going to honour and respect your decision to stop gambling no matter what the reason, so do consider self excluding yourself if you feel you are no longer in control of your gambling activities.
You will also find plenty of charities and support groups that you can make use of and to that are worth seeking help and advice from is GamCare and also Gamblers Anonymous both of which are very well equipped to help, support and guide you to give up gambling once and for all.
Both of those two organisations are going to also offer help and support to anyone who knows or lives with anyone who does have gambling related problem. Please do checkout their websites for more information on the very wide range of services that they offer, all of which are free to make use of.
