its not clear , whats the rule for early bird , whats different between pre sale and next ico? it should be clearly explan.
Let me give you the below example
At Pre-Sale the total amount raised is 55 BTC
At Crowdsale the total amount raised is 465 BTC
Total = 520 BTC
In that case, the overall bonus will be 10% (7% to the Pre-Sale and 3% to the Crowdsale)
Total distributed Quartz will be 82.000.000.
We are witholding the bonus which is 10% (8.200.000 Quartz) and the remaining (73.800.000 Quartz) will be distributed equally to each BTC raised meaning 141.923,0769 per BTC (confirmation - 520 * 141.923,0769 = 73.800.000)
The bonus which is 8.200.000 will then be distributed as below :
The 5.740.000 (7%) will be shared among the Pre-Sale participants which makes the reward per BTC invested equal to 246.286.7133 Quartz
The 2.460.000 (3%) will be shared among the Cowdsale participants which makes the reward per BTC invested equal to 147.213,3995 Quartz
Now, for the confirmation we have to recalculate the above
55 BTC (in the Pre-Sale) multiplied to 246.286,7133 Quartz equals to 13.545.769,23 Quartz
465 BTC (in the Crowdsale) multiplied to 147.213,3995 Quartz equals to 68.454.230,77 Quartz
13.545.769,23 + 68.454.230,77 = 82.000.000 Quartz in Total.
That's one scenario I made based on some given prices.
If I could find some time I will create a similar explanation like the above for all that possible scenarios.
I hope this would help you understand how the distribution will take place.
