if there are only two choices above, maybe I would personally choose Doing an IEO in exchange for but a flat public response rather than a bullshit exchange but the public enthusiastically welcomed it ... why? usually the IEO at the top exchange still has a chance to get good results but in contrast to bullshit exchanges, most of them are just scams. the people who welcomed him were one of the scamers.
Probably happened most of the time, scammers pretend to be the buyers or the one who are supporting the project inside shitty exchange, making things believable from investors eyes. It's better to take the risk using top exchange even the response is in Fiat the chance to grow and success is much higher than shitty exchange where the chance of being scam is high too.
The most important thing to remember is that a popular exchanger will not choose the project blindly. So that their reputation remains good, they will certainly choose projects that have interesting concepts and trusted team. So, even though it has a flat response, I think it is indeed far better than choosing IEO in a bad market.
