You should always be watchful and on alert for others and potential dangers that could happen even in instances when you're not carrying large amounts of money. Also a great reason why online casinos are great, because you can get quick and easy transfers to your own wallet in a matter of minutes in most cases, and unless the site itself or the site's wallet is having problems, you'll be fine.
They have the risk of each and once again to remain cautious even though we use online casino but when we are careless then it is also a loss that we might be trapped on a phishing site. This case is different but basically we have to be wiser in facing every problem arising from gambling so that it doesn't make more losses in the end.
