A crowdsale in cryptocurrency refers to a fundraising method where a project sells their newly created cryptocurrency tokens in exchange for funding. This process involves selling a specific number of tokens to a large number of investors or backers.

The main goal of a crowdsale is to gather enough funds to support the development of a project. This method allows projects to reach a larger pool of potential investors and raise capital by offering their tokens directly to the public.

Crowdsales typically offer bonuses or discounts to early investors to incentivize them to participate. Participants in a crowdsale may receive tokens at a lower price than the anticipated market value once the project is launched.

Investors in a crowdsale can potentially benefit from the success of the project if the value of the tokens increases over time. However, there are risks involved as well, such as the project failing to deliver on its promises or the tokens losing value in the market.
