The main idea of crowdfunding is for investors to pull their monies together to support the launching of a project. Unfortunately people join ICOs as traders not investors so the moment the coin is being listed, they quickly dump them without even waiting for the project to launch any of their products, destroying the price of the coin. Now these same people will come and create a thread here that ICOs are dead. In fact crypto is not dead, we are actually killing it.
Is your main idea to support the project or just to make profit from the bonuses and go your way?
I have joined several icos and I also trade with different exchanges and I thinks it is just human nature and instinct to always hope, assume and expect that you will get some profit from your investment with any ventures. The primary purpose of having an investment is of course to get a good harvest out of your capital so the developer and the entire team must have thought about this already and they should be ready with this kind of happening from all of their investors.
