For example:

Profit is calculated from the total sum pooled together by bettors.

A typical example would be:

John placed a $2000 bet and James placed a $1000 bet that BTC will go higher than $35,000 in 7 days, the Higher Bets Pool is currently at $3000.

Robert places a $1500 bet that BTC will be lower than $35,000 days, the Lower Bets Pool is currently at $1500.

At expiry date if BTC is higher than $35,000 John gets a 66% profit ($2000/$3000 * 100%) from the pooled funds of those who bet for BTC to go lower(contra bets pool), while James gets a 33% profit($1000/$3000 * 100%) from the pooled funds of those who bet for BTC to go lower(contra bets pool).

If BTC is lower than $35,000, Robert gets a 100% profit($1000/$1000 * 100%) from the pooled funds of those who bet for BTC to go higher(contra bets pool).

You lose your total betted money if the trade goes in the wrong direction
