A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.

An initial coin offering (ICO) or initial currency offering is a type of funding using cryptocurrencies. It is often a form of crowdfunding, although a private ICO which does not seek public investment is also possible. In an ICO, a quantity of cryptocurrency is sold in the form of "tokens" ("coins") to speculators or investors, in exchange for legal tender or other cryptocurrencies such as Bitcoin or Ether. The tokens are promoted as future functional units of currency if or when the ICO's funding goal is met and the project successfully launches.

An airdrop is an unsolicited distribution of a cryptocurrency token or coin, usually for free, to numerous wallet addresses. Airdrops are often associated with the launch of a new cryptocurrency or a DeFi protocol, primarily as a way of gaining attention and new followers, resulting in a larger user base and a wider disbursement of coins. Airdrops have been a more important part of ICOs since crypto entrepreneurs have started doing private sales instead of public offerings to raise initial capital. One example of this is by the company Omise, which gave away five percent of its OmiseGO cryptocurrency to Ethereum holders in September 2017.

An Initial exchange offering (IEO) is the cryptocurrency exchange equivalent to a stock launch or Initial public offering (IPO). An IEO is the process of digital asset procurement through an established exchange for the purpose of raising capital for start-up companies. Exchanges act as a middleman between investors and the startup, profiting from fees generated by services rendered during the due diligence process and funding phase. IEO's and initial coin offerings (ICO) share similar characteristics with, however, an IEO can be seen as an evolution from the ICO due to legal influence and an increase in financial regulations within the cryptocurrency market.
A security token offering (STO) / tokenized IPO is a type of public offering in which tokenized digital securities, known as security tokens, are sold in security token exchanges. Tokens can be used to trade real financial assets such as equities and fixed income, and use a blockchain virtual ledger system to store and validate token transactions.
