My husband was winning and losing around the same at first. Only the last few days he hit a lucky streak and won around $12 000usd. After that he couldn’t bet and this is when we made my account.

I will see what happens with this case first before registering to another site. For sure I will never make the same mistake in the future.
The gambling sites would not just let us escape on the basis that you made a mistake. In order to register at a new site, better first learn complete details of its terms and conditions including the KYC policy, the usage of VPN and the gambling site stance on multiple accounts. If you do not pay attention to these, you can end up blocking your account and losing whatever balance you have in that site.
