keeping TR payment

if i buy ship with TR payment what is best way to keep it?

i know about VPN but if i use my credit card it will know its euro and switch my payment straight away?

Yes. it will change to euro all.. I had TR payment and used only one time euro than all changed to euro at the same time.. After 1 month used TR card to buy but it didnt changed to TRY(when I was in Turkey).

Wrote to support about this (becouse the account was opened in Turkey and all other payment were TRY, only one time used euro!) They banned me for some days.. Stupid stuff of sea..

You need to:
1. use a good VPN (Nord VPN, Cyberghost VPN, for example)
2. buy the stuff ingame with e-pin from sites like MTCGame, go there and search Bigpoint)
