Cryptocurrency can be bought in two ways – online and offline. The way of buying, first of all, depends on the jurisdictions (country) in which you are located / working / making a deal / consuming services or content.

Offline services are autonomous terminals (like ATMs), where you can pay with a card and receive cryptocurrency.

Online services can be divided into the following types:

• Exchanges and services that are ready to accept remote payment from you (card, bank transfer, money transfer systems, P2Ptransfer) and in exchange provide you with cryptocurrency to your crypto wallet.

• Private exchange offices, persons in instant messengers or on thematic platforms, ready to accept non-cash or cash money from you (at offline exchange offices) and provide you with cryptocurrency in exchange.
