FAQ
How It Works ?
1/ bitopt.bid is a Hi-Lo betting game, the principle is quite simple , for exemple if you bet "Higher" and if the last spot is greater than the spot you win, if bet "Lower" and then the last spot must be smaller than the first spot.
2/ Spots value are simply the latest blockchain transaction value in btc.
3/ Please try the live demo, it's free.

How to Calculate Profit ?
If you win a bet you can double or earn a percent of your bid amount:

1/ in case you bet "Higher" :
if (last spot / first spot) < 200 then profit = ((last spot / first spot) / 100) * bid price
if (last spot / first spot) > 200 you double your bid price.

2/ in case you bet "lower" :
if (first spot / last spot) < 200 then profit = ((first spot / last spot) / 100) * bid price
if (first spot / last spot) > 200 you double your bid price.
