While traditional online casinos usually require you to register your credit and/or debit card details on your casino account before transacting, BTC casinos run on software that is supported by blockchain, which is virtually impossible to hack.
Additionally, bitcoin casino software typically operates without any human interaction, although some software does require a human dealer.
Many people are skeptical about gambling online and have a preconceived notion that they are vulnerable to hackers and personal information being leaked. On the contrary, bitcoin casinos allow players to remain anonymous and have proven to be more secure than any traditional gambling sites.
Since no personal information is required for crypto gambling, there is no opportunity for your information to be leaked. Moreover, you can remain anonymous, and you can play without concerns of others finding your identity.
