Key Vocabulary

Master The Basic Concepts To Navigate Safely

  • Cryptocurrency

    Cryptocurrencies are digital assets designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. It does not exist in physical form (like paper money) and it is not issued by a central authority. Cryptocurrencies works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database. Bitcoin is the first decentralized cryptocurrency. Since its release in 2009, 8000+ cryptocurrencies have been created.

  • Cryptocurrency Wallet

    A cryptocurrency wallet is a device, physical medium, program or service which stores the public and/or private keys for cryptocurrency transactions. In addition to this basic function of storing the keys, a cryptocurrency wallet more often also offers the functionality of encrypting and/or signing information. Signing can for example result in executing a smart contract, a cryptocurrency transaction, identification or legally signing a 'document'.

  • Crypto Exchanges & OTC

    Cryptocurrency exchanges, or digital currency exchanges (DCE), allows customers to trade cryptocurrencies for fiat money or other digital currencies. Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for cryptocurrencies. Cryptocurrency exchanges typically simply charge fees for each transaction passed on theirs platforms. For customers willing to purchase a large volume of cryptocurrencies, Over-the-counter (OTC) are more convenient. OTC allows the buy and sell of large quantities of Bitcoin and other cryptocurrencies. OTCs offer more private and personalized services to institutions and high net-worth individuals who need a high degree of liquidity and privacy. The key advantage to an OTC is that they handle large trading volumes, such as trading $100,000+ USD without price slippage.
