#AirdropFinderGuide "Guide to Finding Airdrops" was my main source for finding hidden cryptocurrencies for free. Airdrops are like a free lottery ticket, and if you're lucky and have a plan, they can be very valuable to you. I received tokens before they hit the exchanges and saw their prices skyrocket. However, be careful, as not all airdrops are legitimate airdrops. Scammers often use them to collect personal information or to trick users into paying "gas" fees to receive a worthless token.
