Hello,
I have two questions.

First question: When I buy lottery tickets, the amount of BTC per free roll does not increase. What is the problem?

Second question: Yesterday I bought a bonus of 50 RP per roll, but today I could not buy it. In order to buy it, I have to buy more than 4000 tickets or fulfill certain bets. Why is that so?

Thank you in advance for all the advice!
