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...
