I can easily sell the right for 200k on this board.
Apparently, he doesn't consider my offer is 天上掉下来馅饼. Expiration date has passed. :)
As for you, if this is not a 大坑, you need to do some research on the company. If there are a lot of "if"s in the offer, you need to evaluate whether they are achievable.
Good luck.
