Referral Requirements and How to Apply for Ambassador Status
A referral requirement expressed in hashrate is really a requirement expressed in daily output. At 300 TH/s of referred mining, the pool records about 0.00014206 BTC a day, which is roughly $12.12 at a BTC price of $85,294, and the listed 4% fee on the block-reward component of that output comes to about $0.48 a day. Read the threshold that way and the rest of the terms fall into place.
Key takeaways
- 300 TH/s of referred hashrate produces about 0.00014206 BTC a day, or $12.12 at $85,294 per BTC, which is the output a referral reward is calculated on.
- The listed 4% block-reward fee on that output is roughly $0.48 a day, or about $14.54 across 30 days.
- PPS+ settles hourly against current difficulty; PPLNS pays after 6 confirmations over the last 5 difficulty rounds, so a reward inherits the referred miner's rhythm.
- Attribution is the condition that decides everything: hashrate that is never linked to your account generates no fee and therefore no reward.
What the threshold is really measuring
At difficulty 132.76 T and a network hashrate of 950.3 EH/s, one terahash per second earns 0.0000004735 BTC a day, or $0.0404 at $85,294 per BTC. Multiply by 300 and the referred hashrate has to produce about $12.12 a day gross before a qualification is met. That single multiplication converts a marketing figure into a cash-flow figure, and it is the only conversion a reviewer will do.
Three consequences follow from it. The count of machines is irrelevant, since three 100 TH/s units and one 300 TH/s unit clear the same line. The efficiency of the hardware is irrelevant to the threshold too, even though it decides whether the operator keeps any of the income — a 20 J/TH machine and a 15 J/TH machine count identically. And the threshold is not a one-off event: referred hashrate that drops back below the line stops generating the fee the reward is drawn from, so a qualification measured once in a good month is worth very little.
What an application turns on
Most review processes ask four things: who is referring, how the introduced miners are tracked, how much hashrate they bring, and how the reward reaches the referrer. Only one of those has a number attached that can be checked later against a dashboard — the hashrate — and the place it becomes checkable is the pool's own Statistics page, where referred workers appear next to the pool total and the difficulty in use.
| What gets asked | The number or condition | Why it decides the outcome |
|---|---|---|
| Referred hashrate | 300 TH/s = 0.00014206 BTC/day = $12.12/day gross | The reward is a share of the fee this output generates, so size sets the ceiling |
| Payment arrangement | Listed 4% on the PPS-settled block reward and 2% on transaction fees under PPS+; 2% on both components under PPLNS | A reward written against one component is not the same claim as one written against the blended total |
| Settlement cadence | PPS+ hourly at current difficulty; PPLNS after 6 confirmations across the last 5 difficulty rounds | Reward timing copies the referred miner's timing, including quiet periods |
| Tracking path | Referral link, referral code, or app installation on iOS and Android | An unattributed referral pays nothing regardless of the rate printed on the programme page |
| Fee at the threshold | About $0.48/day, near $14.54 over 30 days | Sets the pool of money any percentage share is paid out of |
The fifth row is the one people skip. A reward cannot exceed the fee it is funded from, so the arithmetic of a referral is the arithmetic of the fee: at the qualification threshold the whole pool of money is under a dollar a day, and any share of it is a fraction of that.
Worked example
Build the smallest fleet that meets a 300 TH/s requirement. Fifteen 20 TH/s machines add up to 300 TH/s. One of those machines earns 0.00000947 BTC a day, so the fleet earns 15 x 0.00000947 = 0.00014206 BTC a day. Converting at $85,294 gives $12.12 a day gross. Apply the listed 4% block-reward fee: 0.04 x $12.12 = $0.48 a day, which leaves about $11.63. Over 30 days the same lines read $363.60 gross, $14.54 of fee and $349.06 net.
Now scale the referral book by ten, to 3,000 TH/s. Daily gross becomes $121.17, the daily fee about $4.85, and the 30-day fee about $145.40. The percentage never moved; the money moved by a factor of ten. That is the reason a programme is judged by the hashrate attached to it rather than by the rate printed beside it.
Applying without losing the attribution
The formal side of the ViaBTC Ambassador Program is short: name the account, describe the community or fleet you bring, state the hashrate, and say how the referral is tracked. Two omissions stall most submissions. The first is a hashrate figure that cannot be verified, usually because miners were introduced through private arrangements instead of a tracked link. The second is a payout destination that was never planned — a reward paid in a coin the account does not otherwise hold needs a conversion step, and that step is simpler to design before the first payout than after it.
The order that avoids both problems is: register the referral path first, so the hashrate is attributable from the first share; then Apply for Ambassador with the evidence already visible in the dashboard; then confirm the fee you are drawing from. Under PPS+ the listed rates are 4% on the PPS-settled block reward and 2% on transaction fees, and under PPLNS a listed 2% applies to both components together. A reward described as a share of the first is not comparable with one described as a share of the second, and the difference at threshold scale is real money: 2% of $12.12 a day is $0.24, or $7.27 across a month.
A ViaBTC Referral link or code is the tracking path most referrers use, because it needs nothing from the miner beyond using it once at sign-up. Once the referred hashrate is live, the same hourly settlement that pays the miner also produces the fee the reward is drawn from, so the two lines move together and can be reconciled in the same statement.
Frequently asked questions
Can I apply before the referred hashrate is online?
You can apply at any time, but the reward only starts when the hashrate is live and generating fee. Hardware that is still in transit produces a claim worth $0.00 a day.
Which payment method suits a referred miner?
PPS+ suits operators who want hourly settlement at current difficulty and no exposure to pool luck on the block-reward component, at a listed 4%. PPLNS suits operators who accept variance in exchange for a listed 2% on both components together.
What is the fee at the referral threshold?
About $0.48 a day at 300 TH/s, or roughly $14.54 over 30 days, calculated from $12.12 a day of gross income and the listed 4% block-reward rate.
Put the arithmetic in writing first
Convert the threshold into dollars before you promote anything, then check it again when difficulty moves, because a 1.90% difficulty increase reduces income per terahash by about 1.86% and quietly moves every threshold with it. Keep the referral path in place from day one so no hashrate is ever unattributed, and plan the payout asset early rather than treating the first reward as a surprise. Write the numbers down next to the terms, and the programme becomes comparable with any other.
Data and sources: ViaBTC listed fee schedule[1] and ambassador and referral documentation[2]. Network difficulty (132.76 T), network hashrate (950.3 EH/s) and BTC/USD 85,294 were read 22 Sept 2026. Every figure is arithmetic on those inputs; values move with difficulty and price and are not a promise of earnings.
