Honeypots
In simple terms, a honeypot is a token that has blocked its sales. You can buy, but you can’t sell, so basically the money you invested is lost.
Other kind of honeypots are soft and uses taxes as a method to discourage and block sales. Or simply take massive profit from every sale to the contract beneficiaries, at the expense of regular holders.
Also, a contract that at some moment was NOT a honeypot, can become one later!
