Coinsfera

Coinsfera buys and sells cryptocurrency for cash at an office in Istanbul. The current website explicitly limits its physical presence to that city, and the office is on Necatibey Caddesi in the Beyoğlu district. The company was founded in 2015 and serves individuals.

Assets and currencies The service works in both directions, cash to crypto and crypto to cash. Listed assets are BTC, ETH, USDT, BNB, SOL, BCH, LTC, XRP and TRX, and cash currencies are TRY, USD, EUR, GBP and AED. Payment is made in cash.

Procedure and timing An operation needs identity verification and an agreed time. The company states that a deal typically takes 10 to 15 minutes, depending on the asset and on blockchain confirmation. This suits clients who are in Istanbul and want a settled cash deal in person instead of a bank transfer.

What to confirm The data does not give rates, fees or limits, so a quote should be requested before visiting. Licensing is not described either, and a client who needs documentation for a cash deal should ask what paperwork is issued.
