I think that is a big bonus, most of the projects that I have met that give big bonuses like that experience dump when listing in the market. And most good projects do not provide such a large bonus, because even without a large bonus investors will remain interested in the project because of their good products. If they get 40% bonus, they will sell 20% below the ICO price because they still make a profit.
Indeed, for a early investors and to think that the market is not that wealthy as of now. That is really a too much bonus because some early investors do not really earn that much at first because they do not know how to do it very well. But if you really study every important information, losing money maybe a bad luck only for you. I can surely say that you are well informed in every investing techniques you can really earn.
Honestly giving away unnecessary bonuses will affect a project after, even if the team are very rich investors will dump when they feel like they have too much profits to be earned which means the project gives early investors every reasons to dump the token or coin
Definitely, but that is just only their technique to gain more investors to support their project. Evert project is giving bonuses just to encourage investors to support them.
