Jesus 10% per user is a joke. One of them can dump the price to exactly 0.
10% seems really high. See, if around 2 or 3% is considered usually maximum healthy premine on altcoins, why should buy-inn be any bigger?
The 10% number came from our discussions with DGEX. 10% max investment is what they used for their previous managed pre-sale and what they suggested we implement. We decided that we would take their advice and go with the recommended number they chose from experience.
DGEX did it once and it didn't explode. Also, as I assume DGEX will get compensation based on the amount of invested BTC over DGEX, there is a collision of interests.
Should compensation be based on the amount of invested BTC, the 10% is more self interest than interest in the well being of the coin.
You do have a point and one we had to consider. As per the OP I think the DGEX commission they have set is 3% of funds managed. So there most certainly is a self interest in raising a large amount of funds. That being said, as I just mentioned in another comment, I don't think anyone will hit the 10% mark and the previous high they saw was 6% from one investor.
Of course it is unlikely that the 10% mark will be hit, as it is obvious DGEX wants as much BTC invested as possible.
They will suggest a mark that is so high it is very unlikely it will be hit. That way, the maximum amount of invested BTC from every single person can be guaranteed.
And 6% of all coins in the hands of a single investor is a ticking time bomb already.
NXT had and has to face accusations of bad distribution and their top account only held 5% of everyting.
