I recibed my refound, lot of thanks for your work Sebastian. One question: Why I recibed 16.34 if i pay 17.2 B? What is the calculed metod? (this is not a reproach, just a question

)
Thanks Again¡¡
The payout is 95% because of the great work he did must be honored somehow.
Ok, thanks for your reply... but, I ask again: 780 Bitcoins (avalon price for 10,000 chips) /10,000 = 0.078 B/chip. I paid 0.086 B/chip. I think that all the risk of the operation was in this difference. In 10,000 chips he won 80 B.... and again, this is not a reproach, just a question

I really appreciate the Sebastian work¡¡¡
The difference between 0.078 and 0.086 was the 10%. I didnt refund 95% of 0.078 but of 0.086. So the 10% are changed to 5% for the refunded chips. So if you see it this way i hold 5% and paid back the 10%.
Or do you mean something different?
Funds received. Small tip your way as extra compensation for your efforts (you have mentioned that to be optional I know

)
Thank you!
You have done your calculations wrong:
Your way= SumInBtc*0,95
Right way= 0,082*ChipsAmount.
Like example my case:
60*0,086= 5,16 BTC
1) 5,16*0,95=4,902 BTC (exact amount you have send)
2) (0,086-0,078)/2=0,004. 0,004*60= 0,24. 5,16-0,24=4,92 BTC.
By 5 batches:
50000*0,086*0,95=4085 BTC you will refund your way.
50000*0,082(=0,078+0,004)=4100 BTC
So you will profit 15*100 = 1500 more.
So the 10% are changed to 5% for the refunded chips.
So for refunded chips 10% are changed to 5,375%

I don't really care about 0,018 BTC, just calculations =)
We are at 4 batches refund. One batch and batch 6 are still coming. The fifth batch is at 1506 chips that want to be refunded which is still a way to go till >50%. Except the batches arent delivered and batch 6 comes into the timeframe when we can ask for refund for it. Then we only need 3000 to break this. Of course the other groupbuy involved has to refund too.
The price per batch was 782.1btc with shipping. And the original fee wasnt exactly 10%, it was a bit less. I took it from zefir's GB. I didnt recalculate it but i think you divided the original fee through 2 in order to get 5%. But like i said the chip price was rounded. I only took the buying price from the groupbuy and paid out 95% like asked for.
