A Whitelist is a list of registered and approved participants that are given exclusive access to contribute to an ICO or presale. The benefits of being on a whitelist include early access to purchase tokens at a discounted price and avoiding scams. There are usually strict requirements to be eligible for a whitelist, such as passing know-your-customer (KYC) checks and having experience in investing.The process of whitelisting usually involves individuals interested in participating in the ICO to sign up on the ICO website, provide their personal information and complete KYC (Know Your Customer) and AML (Anti-Money Laundering) checks. Once these checks are completed, the individuals are added to the whitelist and are eligible to participate in the ICO.Whitelisting is often used to limit the number of participants in an ICO and to help prevent fraudulent activities such as money laundering and other financial crimes. By having a whitelist, ICO organizers are able to have more control over the participants in the ICO, which can help to ensure the success of the ICO and the security of the participants' investments.
