1. Initial coin offering

Technology & Computing · Cryptocurrency & Blockchain Abbreviations

A fundraising method in which a crypto project sells newly created tokens to the public, usually for bitcoin or ether, to finance development. It is loosely modeled on an initial public offering but historically had little regulation.

Example: The ICO raised $30 million in a week, but the team never shipped the product.

Mastercoin held one of the first in 2013, Ethereum raised about $18 million in its 2014 sale, and the 2017 boom raised billions, much of it for projects that failed or proved fraudulent. The US SEC's 2017 report on The DAO signaled that many tokens are securities, and enforcement actions followed. Later variants include IEOs and STOs.

ICO files may contain BMP or, since Windows Vista, PNG-compressed images. The related CUR format stores mouse cursors with a hotspot position. macOS uses its own ICNS icon format.
