As a long-term incentive means, options are generally awarded to the core employees of the company, such as senior managers, middle managers, technical backbones, product backbones and operational backbones. Early entry generally refers to the revolutionary veterans before the B round, and the coverage of options will be greater, generally above 60%. Those who join the company later need to be rewarded to employees who are more valuable to the company. Of course, there is full coverage, but there are fewer such companies.
