Auxilium Team has on many occasions says sprouts is worthless.
Why are you even bothering with a swap, since it is apparent many of the sprouts coins holders want nothing to do with you.
Would it not make more sense to just turn Auxilium into a standard ICO and take LTC or BTC or Doge for purchase of said coins.
That way you start your coins and any sprouts users can just sell their sprouts and buy your coin , if they so choose.
This way you avoid the hard feelings that your current stance has caused with the sprouts holders.
Also your ratio in price could be much higher than the 40% if the initial ICO price is higher, and it is not like you can't grant yourselves a premine to cover your costs.
Seems like a simple answer to a simple problem.
