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?
For them getting lucky on one coin will be worth it. For them it is like hitting the lottery, which personally i do not think is called investing but gambling. They are betting on some coins that has low potential. They do not realize they are just making the creator of the coins richer and them poorer. Again before you invest on anything study it. Check if this coin has a real potential.
