Are you desperate for the money ? need an operation, pay the bills etc etc. Then dont bother.
Its not that it may or may not be a scam, its not that bank transfer is safe(ish) its you are unfamiliar with the entire process, and dont automatically know the ins and outs.
If it is a scam and through not knowing the finer details of such a transaction, you lose everything, and you also have no experience on how or who to contact to find out if you can claim money back or ever if you can claim money back.
Somewhere in the region of £500m is lost through bank transfer scams. Just that amount shows those committing them are savvy, and those losing out are not. You clearly fall into the ‘not savvy’ category.
