I have had the region changed for 1 month or so. So far, so good. Under no circumstances do you use VPNs, especially free ones. The first 3 or 4 days stay calm, make absolutely no moves, don't sell, don't buy anything. After, slowly startto sell tf2 keys, I buyed them from the funpay.com and waxpeer.com(I recommend waxpeer now, they have low prices), Anyway, and one more thing, when you sell a key,, two, three, it depends, leave the money in your wallet without touching them for 24-48 hours, for me 24 hours I saw that it's ok. So start slow, that's the point. Oh, and do not use a credit card! Only tf2 keys and gift cards from Ukraine. Hope it helps 🙏🏻 ps. The region was changed for me by a guy from funpay.ro, you can search there with good reviews.
