if you get 30% from FC then just give all your buyers the chance to buy 30% of what they bought, then sort the rest when you get more, or just wait till you get 100%
no need to complicate things, just open orders as soon as possible, order that 30%, cover those who asked for it first.
Then cover the remaining 70%.
Why are we still wasting time? why there is none Trader's book, and address for payments?
Augusto come on!
