then there are cases of scammers, this ICO market has become the gold mine of many scammers and with the constant loss of money investors are losing, and allied to the fact that governments intervene with very strict regulations, it will be even more difficult for any Ico achieve success.
It can't be really avoided when these ICO investors and project/ICO developers collaborate just to gain profit. These ICOs are made even when there's no actual intention to implement what has been stated in their whitepaper or road map because there's big money in it. What's sad is when actual ICOs (and are not scams) which have potential and the actual intention to facilitate change for the world fails to raise enough funds. This sometimes happen when the team poorly plans or markets their project.
OP has surprising statistics as I wouldn't think that it would be possible to measure such data. With the great number of ICOs, I didn't figure that a great majority would be scams. 81% is significantly large so that would mean if it so happens that the ICO you invested in is successful and legit then you are some lucky guy who found a diamond among rocks.
These cycle cant really be stopped if investors do continue do fill out their bags with their money and repeat the process all over again.Nothing to be surprised of that most of projects in the market do have an unrealistic goals or plans.Some might be achievable but would really require too much work or funding and most of them do still fail even on the early phase. This is why its important to see on how dedicated the team behind on the project you are investing and whitepaper or roadmap should really be realistic.
I believe the huge percentage of ICO funds come from the scammers themselves who put their own ETH into contracts to create an illusion of confidence and induce FOMO in potential victims. So, the actual amount of coins invested in ICO's might be going down, despite the seeming popularity of ICO's, but it's still way higher than it should be, people should be treatening all ICO's as scams, and in cases when they are conducted by some big and established entities, they are still insanely high risk investments, because there's no successful ICO's that have delivered a full working product.
