In Dyco investors can ask for the refund but it's not 100%. In this case i can say the investors will get 80% refund and that means the total amounts that have already invested by investors will be reduced 20%.
That means this is better than ICO / IEO. Because at ICO / IEO we can't ask for the slightest refund.
But it seems like if that DYCO is less attractive to developers. Right ?
