The bonus of the token sale seems to be big which to think they almost give it for free. Well, anyway this is how they do the plan and I think the offer seems to be interesting but as the project is new, we should somehow still keep an eye of this project.
I think if that is the case of giving big bonuses that looks too good to be true the team must recheck it again but most of the time big bonuses can attract more investors to join.
