Tokens that have not yet been made public or announced to investors are sold during the ICO presale period. Typically, ICOs impose stringent criteria on buyers in a private transaction. To ensure sure the investor is in line with the objectives of the ICO, they could conduct video calls or interviews. The size of the contribution affects bonuses.
In contrast to crowdsales, the investors in a private sale receive significant perks and discounts. If a token is bought at a discount and sold at the ICO price when token trading starts, investors can make a quick return. Compared to crowdsales and presales, there are more opportunities to purchase tokens in a private sale because institutional investors are the primary target market.
