I think all big casinos start off with that VPN problem, many of them block the access from all VPN because of that. 10 litoshi is not really "small" when considering its just free money given away and that creates a big cost for Erena itself.

I know not many people will reach the withdrawal threshold with that type of money but I am sure there will be at least couple of people who get lucky and reach high bets and withdraw which means free money giveaway from Erena so whatever the amount is I support it just existing.

It also has the usual "test it before deposit" work as well which is what really what its for and that gives a great incentive for people who are on the fence about depositing but they could now test it and decide if they want to deposit or not thanks to the faucet. Also when trying to get the faucet it shows "claim your free 2 litos" but than it gives 10, you may wanna check that.
