Plenty of online casinos are totally reputable and honest. However, as many as 50% may not be so honest.Some have been known to use online gambling software that they can manipulate, not to pay big winners, change the terms of a bonus or to have a non-existent customer support. If you are not careful, your “casino” may be run by a guy without any money from his garage, or they might actually steal your money outright. Having said that, nowadays this instance is not as common as 10 years ago.How do you protect yourself? Do not make huge deposits or huge withdrawals all at once. Only play at honest online casinos.
