Do not share your card details with anyone. Do not use suspicious websites and payment forms. Do not use unfamiliar ATMs to withdraw cash. Try to make out for yourself cards that have the maximum degree of security for conducting Internet operations.
Always adhere to these rules, and you will not become easy prey for scammers. If you are not satisfied with how secure bank is – you can always change the bank for storing funds, but before that you need to think carefully about whether it is worth doing this and whether another bank will be more reliable.
