The competition is too stiff in the top spot. Someone always manage to get 10 step ahead of everyone. 1 Bet of 5BTC in 1.01 odds can secure the top spot in an instant. But is it worth the risk considering a 94.06% winning chance

Now at the time I am making this post, someone has wagered 13.4 BTC while 21 hours left until end of the round. So, it's not that easy to win the daily jackpot.
Let's assume you can secure the first place with wagering 5 BTC in a game with 1.01 odds and 94.06% winning chance.
Usually the winner get about 0.14 BTC. So, If you win, your profit will be 0.05+0.14=0.19 and if you lose your loss will be 5-0.14=4.86
odds=1+(amount of profit if you win/amount of loss if you lose)=1+(0.19/4.86)=1.039
If you win the jackpot it's like that you have played a game with 1.039 odds and 94.6% winning chance.
The house edge is calculated as follows:
HE=1-1.039*0.946=0.017=1.7%
So, even if you can win the daily jackpot with wagering 5 BTC (I don't think it's possible), It's like that you are playing a game with 1.7% house edge.
