It a great opportunity to every one to join in this campaign, since the ICO in this campaign is not too big like other campaign they have an advantages. Then list of participant is limited that's the reason why others make a big profit. They have small amount of budget but every one earn a bunch of gift.
Maybe you are right about that. Others are uncertain of joining since this ICO is not that big but having limited number of participants will be an advantage. As you can see, few are joining because of the small fund. If this ICO will have a small number of participants and if some will not be active, there is a possibility of earning much for every remaining participants.
