This campaign has two sides. The good side is to attract investment. The bad side is the market imbalance. I think the market will be destroyed if there is a 50% bonus. If so, when it reaches us, its price will be lowered very low or nothing.
If you talk about the pre-sale bonuses for early bird investors, it is not the main effect of the dump caused by the earl;y investors. The new projects usually don't take a lesson from the previous bounty campaigns and they usually repeat the same mistakes. It is a commonly known mistake among the teams but the market side of the process is not controllable by any group of professionals.
