in a calculation, investing in an ico project gives us the opportunity to make a big profit. but for now ico projects are high-risk things, some projects fail and that certainly makes us suffer losses. so choose the right ico project and don't lose it.
Unfortunately, most projects are failing. Even the authentic ones are suffering.
You will observe that their prices once they got listed are very low as compared to their private sale or ICO prices.
Dumpers will always be there but come to think of it, they have very small percentage of allotment as compared to the total supply.
So a strong project can't blame it solely to dumpers. If they have robust system, they can easily rise from that dump and achieve their stable price.
And from my end, ICOs are not good way to raise money or get profit from. Very few can offer you that kind of return.
STO are now becoming the new trend. The reliability is better than ICO.
