The code 3STZRUX applies a 5% discount to a GoMining digital miner purchase. It is entered in the promo code or discount field on the checkout payment screen — not in account settings, and not after the order is placed. Because the price of a digital miner depends entirely on the hashrate (TH/s) and energy efficiency (W/TH) you select in the miner builder, the cash value of the 5% is different for every buyer. That is what makes it worth walking through separate cases rather than quoting a single figure.
One thing stays constant across all three: the discount reduces your cost basis. It is not a payout, not extra hashrate and not a return. It slightly shortens the theoretical payback period, nothing more. Mining income itself is never guaranteed, since it moves with network difficulty, the Bitcoin price and fees.
This buyer wants to see how the mechanics work before committing much. They create an account on the website, claim the free bonus miner that new accounts receive, and watch the daily reward cycle for a while.
The catch to understand here: rewards from the free bonus miner cannot be withdrawn until a first miner is purchased. So the test period is informative but closed-ended. When this user does move to a purchase, they open the builder, pick a modest hashrate to keep the total low, and enter 3STZRUX at checkout in capitals with no spaces. Their 5% comes off a small total, so the absolute saving is small — but GoMining codes are generally intended for a first purchase, and this is exactly that first purchase, which is the moment the code is designed to be used.
This user has read that a daily fee for electricity and equipment service is deducted from the pool reward to give the net reward, and that electricity is charged at the project's average rate over the billing period. They therefore care as much about W/TH as about TH/s.
In the builder they push efficiency lower (fewer watts per terahash), because lower W/TH means less electricity used, a lower daily fee and a higher net reward. The estimated daily BTC output and fees update live as the sliders move, so they can compare configurations before committing. A more efficient configuration typically costs more up front, which means the 5% from the code is applied to a larger figure than in scenario one.
The useful way to frame this: the discount is a one-off reduction at the moment of the transaction, while the efficiency choice affects the daily fee for as long as the miner runs. The code helps with the entry price; the W/TH setting helps with the ongoing arithmetic. They are separate levers and both are set before checkout.
The same account works on the website and the mobile app, so this buyer configures a miner on desktop, then completes the order in the app. The redemption path does not change: open the miner builder, set hashrate and energy efficiency, proceed to checkout, find the promo code field on the payment screen, enter the code, and confirm the total updates before paying.
The point this user should not skip is the confirmation step. The code is applied at the moment of the transaction, with no post-checkout action available, so if the total has not visibly changed, the order should not be completed yet. Payment methods vary by country and should be checked on the checkout page itself.
The code goes in at checkout, on the payment screen, in capitals with no spaces.
The saving is proportional, so it scales with the configuration chosen in the builder.
The discount applies to the purchase made while the code is attached to the account.
After payment, the miner begins accruing rewards on the daily cycle, with the maintenance fee deducted from the pool reward.
Different budgets and different configurations change the size of the saving, not the method. In each case the decision that matters most is the TH/s and W/TH combination; the 5% is applied to whatever that decision produces.
