With regard to IDO, the very idea sounds good. It seems like there is a guarantee that we will not be dumped for money (as is so far happening in the same blockcollider, where my money has been frozen for many years). Let's see if the designs shoot this year!
The idea sounds horrible in my opinion. IDO doesn't have a regulator unlike IEO(which is the exchange) in terms of filtering projects. This sounds like an easier way for the scammer to run away with investors' money. Remember not all ideas is good especially when it comes to investment. This may sound attractive but it is the same as ICO but just using a decentralized exchange where scammers have more freedom of action.
actually that is the main issue for me when it comes to IDO. as they are using decentralised platform, basically, everyone can participate in this market. and i am certain, a lot of scammers will be there as well. unlike with ieo, this type of fundraising at least has some restrictions and it is according to the exchange how tight they will be with respect to their requirements. thus, i think IDO will just be another great playground for these scammers.
