OneSwap, a decentralized trading platform, will launch a new feature called Prediction on April 29, 2022, and BTC/USDT will be the first prediction market where users can win prizes by betting on the price trend of BTC/USDT. Prediction comes with an initial prize pool of as much as 1 million CET. Meanwhile, OneSwap will also launch the “Win Rate Ranking Reward Game” that will allow users to receive double rewards.

Once a bet has been submitted, the user needs to wait for the current round to end. If a user bet on the right price trend, he will get back his bet and earn prizes (note: users may withdraw their prizes for multiple rounds cumulatively, and prizes will remain valid indefinitely); if he bet on the wrong price trend (i.e. he bet on the opposite direction or the Locked Price equals the Settlement Price), then the bet will be transferred to the prize pool.

Here, we will illustrate how prizes are distributed via two examples:

Let us suppose the transaction fee stands at 5%, and the initial prize pool contains 1,000,000 CET.

The first round:

Of the two participants, one bet 10,000 CET and won; the other bet 5,000 CET and lost.

l Winner: Initial Bet + Prize (with the transaction fee subtracted) =10,000+10,000×0.95 = 19,500 (CET);

l Loser: 0;

After the first round, the prize pool now contains 1,000,000-9,500+5,000 = 995,500 (CET).

Suppose the transaction fee remains at 5%, and the initial prize pool now contains 995,500 CET.

The second round:

Among the 201 participants, 200 bet 10,000 CET each and all won, and one participant bet 5,000 CET and lost. In this case, since there is not enough CET in the prize pool for all the 200 winners (9,500 CET
