Re: When I received the token, should I sell it immediately, or what? How do I judge
When you receive a token, you should not sell them immediately. If everyone sells their token immediately when they receive it. This causes them to fall sharply. There will be no chance for that token to grow. So be patient and wait. By the way, keeping them makes you more profitable. 
Bounty hunters get 2% -3% of the total pool of tokens, with all the desire, they will not be able to bring down the price. The price is always brought down by investors who first seek to sell their tokens and discourage investments.
