I know they should be using these international betting platforms with VPN because of this new law by the India government, this leads to many scam victims when many Indian will really pull through into finding international gambling sites which they may fall under some fake platforms.
Not everyone knows all these features you mentioned about a gambling site, some people are naive and doesn't look out but proceed to deposit and and start playing.
In last few years India was getting one of the biggest sports betting sites heaven which was taking huge funds and huge number of players due to this strict law now things are problematic because government can use many ways to monitor which will increase risk for gamblers but with this now illegal use of these sites will be also increased.
VPN could be helpful while casinos surely will do some better way for them because they will never want to lose huge number of users due to few restrictions while this sudden decision is surely going to be had negative impact on many sites because Indian sports activities have good boom in last few years and things were looking for them ideally to have their share and also give good investment to these sports organizations for bringing more competitiveness and entertainment.
