Hi Product Hunt, Yodoya is a simulated crypto trading challenge. You trade a simulated account on live prices, and if you hit the target before either loss limit, you earn a share of the simulated profit in USDC. The inconvenient part first: most people don't pass, and Yodoya is new, so no payout has settled yet. When one does, it goes on our public ledger with its on-chain transaction hash. Why build another one? Most prop-style challenges stack up rules until passing is about the rulebook, not the trading. Yodoya has three: +10% to pass −4% max loss in a day −5% max loss overall, a floor that stays put and never trails your equity No time limit, no minimum trading days, no consistency rule, no news or weekend bans, no reset fees. Challenges start at $21 for your first, and the fee comes back in full until you place your first trade. No ID to sign up, buy, trade or withdraw. Before you pay anything, there are two free 1v1 games: Chart Draft: you and an opponent take turns claiming stretches of one finished chart as trades, then swap seats and replay it. Nothing hidden, nothing random. Play a bot with no account. Live duels: you vs another trader on live prices, 15 to 60 minutes, higher equity at the buzzer wins. Free for now, no entry and no prize. The name comes from the Yodoya merchant house, whose rice market in Osaka became the Dojima exchange, where the candlestick chart began. I'd love to hear what you'd cut or add, and what would make you trust a challenge like this.
