They can't give tokens for basically free, as I said before, if a project is good enough, sells even without bonuses, it's just a fact. I've seen ICOs with 100% bonus not even reaching the softcap in the past
exactly, great bonuses, great future problems with eventual evictions, there is potential to sell well without exaggeration of bonuses, in addition, the marketing well applied and a market improvement will cause that many that already accompany the project bring more investments soon
If such a system would exist, everybody would use it. All systems have advantages and disadvantages, but if a project is really good in the longterm it doesnt matter which system they had used.
