It does not even correspond had I invested in today
According to maths
9725.7 BTC / 85.000.000 waves = 0.00011442 BTC per wave
Had I invested now I should have then
2.8 BTC / 0.00011442 = 24471.2463
my balance is 22925.07926960?!
On top of that the transaction in my admin panel is created at 13:59:09 Paris Time (11:59:09 UTC)
The transaction in the blockchain is 11:58:18 UTC
The 20% Bonus ended at 12:00:00 UTC
Bitcoin 2.80020000 TXIDXXXXXXXXXXXXXXXXXXXXXX 2016-04-13 13:59:09 2
So my balance should be 20% of 2.8 BTC = 0,56 BTC + 2.8 BTC = 3.36 BTC
3.36 BTC / 0.00011442 = 29370.6294 waves ?!
"9725.7 BTC / 85.000.000 waves = 0.00011442 BTC per wave" would be true only if there were no bonuses at all.
(9725 + 1240) BTC = 85 million Waves is the true equation, 1240 being the sum of the bonuses. If you calculate your balance using this, you'll arrive at a much closer value you see in your account.
