Scammers have no mercy and that's their job, they will try to do anything to cheat until you don't realize that you are part of a scam victim, generally the targets of scams will not be much different:

- ICO/IDO scam
- Phishing
- Wallet/Exchange scam

To avoid scam then "Control greed, multiply knowledge".
