Bet online can be very safe or very insecure, it all depends on where and how you do it. There are casinos who take advantage of their users and sell their data, they supplant their identity or kidnap their money. Luckily, this is not usual, but that is not usual does not mean that it can not happen. To avoid it you must always enter casinos that have a license and seals of international or national evaluation agencies. Take a look at the Casino Safety section - Casi all serious casinos have pages in which they speak of their security systems - and find out about the protocols they use. You can also search for reviews on the Internet, because nowadays the bad news run as the gunpowder and, if someone has had a problem with a certain operator, it surely has published it on the network.
