Frequently asked questions
Cryptocurrency is a digital or virtual form of currency that uses cryptography for secure transactions and to control the creation of new units. It operates independently of any central bank or government, making it decentralised and resistant to censorship or manipulation.
Cryptocurrencies like Bitcoin, Ethereum, and Litecoin are based on blockchain technology, a distributed ledger that records all transactions in a transparent and immutable manner.
To sell and buy cryptocurrency, you first need to choose a reliable cryptocurrency trading service. We offer a bespoke, tailored, and human-led onboarding process, delivered by teams with deep sector expertise. Upon completion, you can immediately begin using our service by simply requesting a trade with our team via your preferred communication channel.
When trading cryptocurrencies through the ONE.io OTC desk, users will be in contact with their trading expert until the trade is complete. The trading expert will request that the chosen cryptocurrency be delivered to an internal wallet, from which the exchange will be completed.
