An Initial Coin Offering (ICO) is a modern fundraising method for start-ups, similar to crowdfunding but using digital tokens instead of traditional cash or rewards. Investors purchase these tokens, which they can later use to buy the product or resell for potential profit. ICOs provide entrepreneurs with a global financing opportunity while offering investors early access to innovative projects. Overall, ICOs connect entrepreneurship, finance, and blockchain technology, making them a revolutionary tool for start-up funding.
