Every cent matters
Predictions resolve at cent precision, making each round a quick test of market intuition rather than a long-term trade.

The idea
Three steps. One perfect prediction.
A fast, simple format: choose your price, lock your prediction, and see how close you came when the round settles.
01
Pick your price.
Choose the BSV/USD price you think we'll see at the end of the next 10-minute round. Accuracy goes all the way down to a single cent.
02
Lock it in.
Entries are open for the first 2 minutes of every 10-minute round, so each prediction is at least an 8-minute call. Your pick is hashed in your browser and committed before entries close; it is revealed automatically, so keep the tab open.
03
See who nailed it.
When the round ends, your prediction is compared with the settlement price. The closest revealed prediction wins the play-credit pool; ties split it.
Built around trust
Small stakes. Serious transparency.
A simple game deserves clear rules, reliable data, and results that can be verified independently.
Designed for blockchain
BSV micropayments and cryptographic commitments are being explored for a future regulated version of the platform.
Verifiable results
The envisioned settlement engine would publish the oracle rules, accepted commitments, and an auditable record of outcomes.
Ten-minute energy
Fresh rounds throughout the day. No complicated positions or long wait for the next chance to make a prediction.
Good to know
Frequently asked questions.
Is PennyPredict a real-money game?
Not yet. The first 24 hours are a free launch period with play credits that have no value: nothing is deposited and nothing of monetary value is paid out. The plan is for a paid entry to cost one US cent, paid in BSV at the exchange rate at the moment you pay. That only opens after a legal review and a final round of testing.
Are the prices on this page live?
Yes, with limits. The BSV/USD price comes from the WhatsOnChain exchange-rate API and can be a minute or two behind the market. It is a single source, which is fine for a free game but not enough for real money. If the feed is stale or missing at settlement, the round is voided and everyone is refunded.
What if two people predict the same price?
Equally close winners split the pool equally. Any leftover credits go one each to the winners in a fixed, published order, so the result is the same every time it is replayed.
What does the one-cent entry mean?
One cent per prediction is the proposed concept for a possible regulated game, not a charge on this website. No payment integration is present in this prototype.
How are results verified?
Your prediction is hashed in your browser and committed before the entry window closes, then revealed automatically. Each finished round publishes an evidence package (every commitment, every reveal, the signed price and the price observations behind it, and the payouts) that anyone can replay independently. Writing each round's fingerprint to the BSV blockchain is built and tested but is not switched on for this public site.
