At Quark, you don’t have to make an appointment in advance for a transaction!
Just show up at our stationary bitcoin exchange offices, which are available in many Polish cities, to make a transaction to buy or sell cryptocurrencies. We provide fast and hassle-free exchange on attractive terms.
We do not record or store personal information about our customers. All transactions made at our stationary exchange offices, whether buying cryptocurrencies or selling cryptocurrencies, are fully anonymous.
We provide a fully secure cryptocurrency exchange process. All transactions are carried out with the latest cryptographic standards available in blockchain technology. We guarantee secure purchase and sale of cryptocurrencies.
Quark exchange offices handle the exchange of various cryptocurrencies including: Bitcoin (BTC), Ethereum (ETH), stablecoins USDT (into ERC20 and TRC20), USDC (into ERC20) and Tron (TRX), into PLN. The process is similar to a traditional currency exchange at places dealing with euros or dollars.
Transactions at our Bitcoin Quark Exchange Offices are swift and typically take on average just a few minutes. Our proprietary cutting-edge software ensures secure and instant transaction processing. New customers receive a helpful introduction to the world of cryptocurrencies and essential security guidelines.
To make a transaction, all you need is access to your cryptocurrency wallet. If you’re buying cryptocurrencies, you’ll need your wallet address to receive the tokens. If you’re selling, you must be able to initiate the transaction from your wallet to our designated address.
Yes. In general, there are no limitations at our exchange offices. However, on rare occasions, for example, a specific exchange office might temporarily lack the required amount of cash to complete a transaction, but this is very rare.
Another aspect to consider is our requirements related to AML/KYC, which become more strict as the value of the transaction increases. We follow the standard limit of EUR 1,000 set be the European Union for cash transactions, or a series of linked transactions. Above this limit, we are required by law to verify the customer according to the applicable AML/KYC regulations. Transactions exceeding the equivalent of EUR 15,000 require reporting to the General Inspector for Financial Information (GIFI).
Certainly! During our office hours (typically 10:00 am – 6:00 pm), you can make a transaction without an appointment. Feel free to call beforehand to discuss the details if you prefer.
A cryptocurrency exchange office is a secure place where you can buy or sell cryptocurrencies for cash, anonymously. The chain of Bitcoin Quark Exchange Offices offers a secure and anonymous environment for quick cryptocurrency transactions.

Each local franchised exchange office is registered with the National Tax Administration (KAS) in the register of companies trading in cryptocurrencies.
