What we see here is that it is a crypto exchange shop, where various crypto currencies including Bitcoin are exchanged. However, Turkish people will benefit a lot from exchanging bitcoins here and it is a very good initiative. But this goal is not bad, but no goods are sold here, only virtual currencies are exchanged for local currency. If you want to buy goods with bitcoins, you must go to a store that accepts bitcoins. But in my country bitcoin is a legal offense for which bitcoins are not accepted anywhere, and there are no crypto exchanges and stores.
Turkish people already use big exchanges such as TRBinance and BTCTürk and deposit/withdraw/trade with low fees. Why would anybody want to use these shops and pay high fees? These are built for tourists.
Exchanging any amount of coins you want in a foreign country for the local currency without having to answer to anyone attracts many tourists. They don't mind paying 5-10% commission, unlike local people.
