Is it compulsory or not to write on the forum to those who do not buy tokens, but only distribute information about the company on social networks and is a member of the bonus program?
If you're a part of the Bounty program, then you only have to follow the terms you signed up for, so if you're supposed to re-share on Facebook then that's all you have to do, if you signed up to share on Bitcointalk the you do that and so on.
Does it mean that I don’t need to purchase tokens during the ICO in order to take part in the bounty program?
