I made a fatal miscalculation - i calculated 90k revenue / 8 hours / day and i not calculated with seats (3x) - so i stopped to selling boosters and will cover my loss from my pocket - this is my tax for the non sleeping and coding..
all bough boosters will stay (i will pay for my mistake)
after 1 month - when boosters (99%) will end, i will add boosters again with changed ratio...
Only yesterday I've made ~400k, for me it's ok if you want to refund the booster via paypal (I don't know if I can refund, from history of paypal I see only "Report" option, is this?)
