There has got to be a lot of dumps after this token is listed on exchanges knowing those guys got about 50% more. I find it not too good to invest to such scheme. It fees like the team isn't so much confident about their project that they are selling with so much bonus. 10% would have been fine but 50% is another story.
this is why i pass ico which offer 50% discount, if project is interesting i wait for them to buy on exchanges. i will buy bbos on exchange at steep discount.
how much has bbos collected in pre sale, will this information made public?
