So 0.01BTC..
Of course no one will want to buy any of this premined coin at that price so you will get no buyers, and lots of sellers.
As for making it impossible - are you going to check every message everyone sends?
I'm not sure you have really thought this through - or maybe you have, and you just want to cash in the premine.
Where did you read that premined is for sell ?!? ROFL ... in the OP you say ...
The IPO is open right now, its return on investment is 200% one day before launch.
That really means, that for example for 1 BTC invested you will have 200 UNV (instead of 100 UNV), one day before the launch.
Every investment is insured up to 100%.
Minimum IPO invest is 1 BTC.
So you are offering to sell the premine coins at 0.005 each ...
(and just to remind you that is HALF the claimed MINIMUM value for UNV ...)
Yes it's only for the IPO, As we are devs we can do such a thing BUT when UNV will be sold on exchanges, then it will be 0.01 BTC minimum value.
