payment confirmed within minutes after gates opened but allegedly not in the 20% discount range. is there a way to validate? hard to imagine, especially because we´re less than 2% over 20% discount threshold even now....
ICOs with these early bird bonuses are really starting to look very dodgy.
I don't think you can validate it without knowing all the addresses generated for the ICO.
I don't think you can blame the developers for the slow confirmation time, it is based on first come first serve and can't expect someone that the Bitcoin is unconfirmed to get early bonus ahead of someone who uses high transaction fee and is transaction was confirmed early
