Interesting to see that they start providing option to earn interest on your balance.
The lottery is provably fair, however, unfortunately haven't won anything till now(((
Until now system was not fair so don't know how they were selecting the winners but now they made a better system so we can try our luck. But as we all know, the winning chance in a lottery is very low and one should be very lucky to win that first price. Just try with a small amount every week to check your luck.
Plus buying the lottery tickets increases your achievement towards next bonus. I'm buying tickets from everything I claim until I increase my bonus.
