Your Sprint Challenge does not start at the time of purchase.
Before you can begin trading, you must first complete the required KYC verification and contract signing. These steps must be completed before the account can be traded.
Once your KYC has been approved and the contract has been completed, your Sprint Challenge will begin when you place your first trade.
This means you can purchase the account first and begin only when you are ready to trade. Once the first trade is opened, the selected time limit begins immediately.
From that moment, the challenge is live and must be completed within the chosen timeframe.
