The more important question would be, are you sure you want to. We don’t advise it. There is opportunity, but there is huge risk.
An ICO, or Initial Coin Offering, is a process by which a new project sells their newly-minted crypto-tokens, often in exchange for Bitcoin or ETH.
This is similar to crowdfunding, or an IPO (Initial Public Offering) where a start-up sells to initial shareholders. This appeals to ETH holders because they can trade their ETH for a portion of a company’s crypto-assets at a discounted price against what the assets *may* be valued at when the new tokens are made public. If all goes well, the owner of these new tokens can choose to sell when the project goes public, and if the project gains traction in the market, this can generate a hefty profit. If things don’t go well, however, and the new tokens are deemed worthless by the market, the ICO participants are liable to lose.
If you are convinced you really want to explore ICOs, you can find a list of ICOs here.
