An initial coin offering (ICO) is the equivalent of an initial public offering in the cryptocurrency sector. A company looking to collect cash for a cryptocurrency creation service, such as the creation of a new coin, software, or service, may conduct an ICO.
When the blockchain is first put into operation, the total number of coins that will be mined is referred to as the original issue value. The total quantity of blockchain coins that will ever be mined is the maximum issue value of the cryptocurrency. Bitcoin, for instance, has a maximum issue value of 21 million coins but an initial issue value of zero coins when it first became available.
