Has anyone benefitted from cryptocurrency tokens

Before a new crypto currency is launched in the market and before it is sold through ICO (Initial Coin Offering), the creators of crypto currency offer free coins as crypto currency tokens. Users can get these tokens through various tasks like joining the official site of the crypto currency, following their social media accounts, promoting the coins, and bringing referrals. After he token sale end, ICO is launched, and after the ICO ends, the crypto currency is officially launched through an Exchange. Has anyone received free coins through token sales?
