人生能有几次搏?愿start 能up, 公司前途自己判, 股权当听云河说.

Start up offers the best finance reward if it can be UP in the future.
Anyway, take the chance if you did your homework and believe it will be UP.
I will try to ask 5% to 10% (it may be high or low, totally depends how important u r in the company) of the total share since I carry a CTO title.

Thanks!
