This is good to know
I would like to know how much to spend to decide, I don't want to just start spending and hoping for the best before knowing exactly how much.
What is the point if it is going to cost me half of what I got?
That's not how gambling works. Try thinking about how much you might win.
Well, the odds are against me, it isn't me who leaves things to chance.
Thanks again for the answers.
I can give you a rough estimate:
Since I just crossed the border between getting the full reward and not I know I'm quite close to the border.
We know that we need 50$ deposits to get the full reward, we further know that lottery tickets are weigthed with 20, the wagered amount with 4 and that both are being put into relation to the amount we earned from free rolls. The only thing we don't know is the weigthing of it. By some calculations with the amount I had when I crossed the border I calculated this weigthing to be about 14. This means that the sum of the amount spent on tickets multiplied with 20 and the amount wagered multiplied by 4 has to be 14 times as high as the amount earned from free rolls.
Of course this assumes a linear correlation, but I would be very surprised if the correlation were'nt linear.
In the end this means you would have to spent either 70% of the amount earned from free rolls on lottery tickets or wager 3.5 times as much in multiply assuming you have no bitcoins in your account!Of course these are just rough calculations, but they give you a feeling for how much you have to spent to get the regular reward.
