How to Mine Groestlcoin (GRS) in 2026
Updated June 2026 · Beginner-friendly · GPU (AMD & Nvidia) mining guide
Groestlcoin (ticker GRS) is a 2014 fair-launch coin best known for being first to activate SegWit and for relentless wallet engineering. For miners, its claim to fame is the Groestl algorithm — one of the most power-efficient proof-of-work algorithms a GPU can run. Cards mine GRS cool and quiet at a fraction of their normal gaming wattage. This guide covers how Groestl mining works, what hardware to use, and how to get from zero to your first payout.
To mine Groestlcoin (GRS), install a Groestl-capable GPU miner (WildRig Multi for AMD, ccminer for Nvidia), create a GRS wallet (Groestlcoin Core or Electrum-GRS), and point the miner at a Groestlcoin pool with your address as the username. Groestl is exceptionally light on power — GPUs draw far less than under most other algorithms — so electricity-adjusted margins are the main attraction.
What is Groestlcoin and how does mining work?
Groestlcoin launched in March 2014 with no premine and no ICO, and has shipped software upgrades continuously ever since — it was the first coin to activate SegWit (January 2017) and has stayed at the front of Bitcoin-derived protocol upgrades. The coin targets one-minute blocks with a maximum supply of 105 million GRS.
Its proof-of-work uses Grøstl-512, a SHA-3 finalist hash. Computationally it is remarkably cheap: GPUs mining Groestl draw noticeably less power and run cooler than on nearly any other algorithm. That makes GRS a favorite for miners optimizing efficiency (J/MH) rather than raw revenue per card, and a practical choice in warm rooms or on power-limited circuits.
Mining software: WildRig Multi covers AMD cards; ccminer (the -djm34 or alexis builds) covers Nvidia. Both are free, command-line miners where you set the pool URL and your GRS address.
How to mine Groestlcoin: step by step
-
1. Check your hardware
Any reasonably modern AMD or Nvidia GPU can mine Groestl — there is no large memory file to hold, so VRAM is not a constraint. Because the algorithm is so power-light, efficiency-focused mid-range cards do very well.
-
2. Create a Groestlcoin wallet
Download Groestlcoin Core (full node) or Electrum-GRS (light wallet) from the official site — the project also maintains mobile and hardware-wallet support. Generate a receiving address and back up your seed phrase offline.
-
3. Get a Groestl miner and pick a pool
Download WildRig Multi (AMD) or ccminer (Nvidia). Choose a Groestlcoin pool with a low fee and a payout threshold you can hit quickly — GRS pools are small, so a steady PPLNS pool beats chasing the largest one.
-
4. Configure and start mining
Launch the miner with your pool's stratum URL and port and your GRS address as the username (add .workername to label rigs). You should see accepted shares within a minute, with the GPU drawing notably less power than under other algorithms.
-
5. Tune for efficiency and watch profit
Groestl already runs cool, but undervolting still helps the J/MH figure. Track your daily yield against your power price — GRS is a small-cap coin, so revenue moves with both difficulty and the token's market price.

How to check your Groestlcoin mining profit
Profit is revenue minus electricity, and both move daily. To get a number you can trust:
- Set your real power rate. The same hardware can be solidly green at $0.10/kWh and red at $0.25/kWh. Our electricity cost guide shows how much it swings the result.
- Use live numbers. Price, difficulty, and network hashrate all drift. Track them on the live Groestlcoin mining page before and after you commit hardware.
- Compare against alternatives. The same hardware could mine another coin — or in the case of GPUs, earn from AI rental. See GPU mining vs. AI rental and the rig leaderboard.
Is mining Groestlcoin worth it? The honest take
- Best-in-class power efficiency. If your bottleneck is electricity cost, heat, or circuit capacity, Groestl is one of the friendliest algorithms in mining.
- Small pools, small cap. GRS markets are thin — both pool hashrate and exchange liquidity are modest, so treat revenue estimates with care.
- Serious engineering pedigree. First SegWit activation and a long unbroken release history — the project is a survivor, not a pump.
- Efficiency beats throughput here. Rank your cards by J/MH on Groestl, not raw hashrate, before deciding what to point at it.
