So saw many self airdrops of ERC20 tokens and wave platforms in social media. They would promise their investors a cheap token price purchase, and in turn promise a good listing price at the exchange. 98% of these self airdrop never make it to exchange, and the few that get listed in a decentralized exchange get pumped for 2hrs and there after dumped forever. Why do you think people still patronize these scamming project and not study good ICOs and buy?
