There are two potential reasons for this:
1. The minimum amount for withdrawal is 10 USDT (the equivalent in BTC). Check that you have mined at least this amount. Please note that when the price of Bitcoin changes, the amount in USDT may also change, mining is running in BTC and is equivalent to USDT.
2. The mining process is still active. Withdrawals are not possible while the mining process is still ongoing. If mining is still running, wait until the end of the active session and then click the 'Withdraw' button.
3. If you have issues with the Crypto Miner, we recommend that you check your Internet connection, connect to a stable Wi-Fi network or reinstall the StormGain app.
