ICO stands for Initial Coin Offering. It is a the fundraising event of EBCF’s AMACOIN offering. It's similar to an IPO (Initial Public Offering) which raises funds when a new company ventures onto the stock market.
IEO stands for Initial Exchange Offering, and is conducted directly on the cryptocurrency platforms (exchanges). Contrary to the ICO, an IEO is administered by the crypto exchanges on behalf of EBCF Green Assets Switzerland SA to list the token during its issuance or during a sale event of the tokens in reserve.
