Polymarket has quietly set up 5-minute Up/Down markets for cryptocurrencies including Bitcoin (BTC), Solana (SOL), Ethereum (ETH), and XRP. Although trading is not yet live, the infrastructure is reportedly ready, with high-frequency trading bots like gabagool22 poised to capitalize once the markets are activated. Development and testing wallets, identifiable by their numeric suffixes, have been used in the setup process. These wallets are mostly empty, indicating their use in the preparatory phase. The launch of these markets is expected to significantly enhance the trading dynamics on Polymarket, particularly for automated trading strategies.
