Hi,

I try to increase % for FREE BTC rewards in Freebitco.in.


prntscr.com/iblgdc
"Play MULTIPLY BTC or buy lottery tickets to increase your FREE BTC rewards by up to +0.00000456 BTC
35.4296% achieved towards the next +0.00000024 BTC bonus!"


When I began to buy lottery tickets, each ticket increased that rate by 0.00054%. Now that more than 72,000 satoshi have been spent - one lottery ticket increases the percentage by 0.00036. At the same time, in the beginning, each freeroll satoshi decreased the percentage by -0,00012, while now (72,000 satoshi later) - decreased by -0,00023.


Can anyone explain why this is happening. What does it depend on?
