It is true,you get 1 GT for every 0.005 Bitcoin wagered (not gambled) but wagered including the amount you win during gambling.There is no need to record anything as you can check the activity in the daily jackpot and see that the amount gambled there is much higher these last days than it was before,for me this is a clear indication that more and more people are giving it all to get as many GT tickets as before.
You're right. Users have really been collecting golden tickets much more actively. By the way, there are only 4 days left until the end of the current round of the Lambo lottery, and the total number of tickets has already exceeded 1.6 million. This is already much more compared to the previous round. Therefore, this time the chance of winning the Lambo will be significantly less.
I don't think it will be significantly less although based on mathematics and probability you are right.The fact that there are more tickets than last time around add to this thinking but the truth is that even people who hold only 1 Golden Ticket have chances to win the draw.
Of course those who have more tickets here are more favored as it is different than the weekly lottery where not all the users have tickets here different from there where almost everyone has one ticket at least.
