A VPN subscription isn't that expensive and can start as low as $3-4 per month if paid yearly. It's not a huge amount of money, but I can understand why someone may prefer not to burden their budget with services that are not 100% necessary; I'm not blaming you, as I'm not paying for one either. I have no issues with Betpanda, and I'm simply using a private DNS, which masks your IP. It's a setting you can easily alter in Chrome, and BetPanda is restricted in my country as well. So far, I've had zero issues whatsoever.
I have never subscribed to a VPN only for casinos but have subscribed for other needs as well, if for example to bypass restricted casino sites then it is better to find another casino than to force it... But fortunately Betpanda has no restrictions for my country.
Well... to use DNS I did it with Cloudflare WARP - using this did not have any problems.
