The easiest way to avoid all the nonsense from crappy online casinos is to follow the steps of others on this forum, avoid all online casinos that are not on this forum, use stake.com, Roobet, and other popular casinos on this forum and you will be fine, there will be less craps from casinos and you will have a good experience gambling online, most newbie oy learn after they use some random online casinos they found while surfing the internet, do not be like them.
Also, make sure you send the exact amount you are prepared to lose into any online casino's account, there are a few reasons why this is important, some people turn addicted this way because they believe they have a lot of money but they are not ready to lose it all, once they use the whole balance to gamble they will have no choice but to try chasing their losses which will eventually leads to more losses.
From this point on, they will start engaging into things they aren't used to before, like borrowing money from friends and people around them, promising to pay them back sooner, and if they lose such money that's where problems will evolve, they will start sneaking around with debts.
