GRIN Wallet Guide: Helping Miners Get Started
In December, we published a detailed step-by-step guide explaining how to use the GRIN wallet correctly. GRIN remains one of the coins that can be very profitable to mine, but it also causes constant confusion among miners — especially those encountering it for the first time.
The main issue is that GRIN cannot be mined directly to an address generated on a cryptocurrency exchange. Instead, miners must use a local GRIN wallet and properly configure transaction methods such as HTTP or file-based transactions. This additional complexity often leads to setup errors, failed payouts, or miners abandoning GRIN altogether.
That is exactly why we created this guide — to walk miners through the entire process step by step and remove unnecessary friction:

If you are mining or planning to mine GRIN, we strongly recommend reading this article carefully.
Clore Mining Has Ended
We regret to share extremely unpleasant — and frankly unacceptable — news regarding Clore (Clore.ai).
The Clore team has unilaterally ended mining and migrated the project to an ERC token. Mining beyond block 1,584,180 is completely pointless — everything mined after that block belongs to a fork that is not supported by any exchange.
What makes this situation especially troubling is how it was handled. The Clore developers never contacted mining pools in any way. There were:
- no advance warnings,
- no technical notices,
- no timelines or transition plans.
As a result, a huge number of miners and pools unknowingly continued mining a worthless fork. The only communication from the Clore team was an after-the-fact message on Twitter saying “thanks to the miners” — a platform that many miners do not even follow.
This approach is deeply disappointing. This is not how things are done, and it is not how you treat the pools and miners who secured and supported your network.
As a direct consequence:
- all Clore pools were shut down immediately;
- no further payouts are possible;
- a significant amount was already paid out into a worthless, unsupported fork.
This situation came as a shock to us as well. While we sincerely apologize to all affected miners, the responsibility for what happened lies entirely with the Clore.ai management and development team.
Please switch to mining other coins as soon as possible. Use 2CryptoCalc to find suitable alternatives based on your hardware.
Kaspa (KAS) Block Reward Reduction
In accordance with the Kaspa Tokenomics, the Crescendo Hard Fork, and the official emission schedule, Kaspa underwent another scheduled block reward reduction in December.
- Previous Reward: 3.89 KAS
- New Reward: 3.67 KAS
Please pay attention! Kaspa mining profitability has changed accordingly. We have already updated 2CryptoCalc so you can accurately recalculate your expected доходность.
Year-End Recap: Crypto Mining in 2025
As 2025 comes to an end, it is clear that crypto mining continues to evolve — not always in easy or predictable ways.
Unfortunately, many small and poorly managed cryptocurrencies did not survive this year. Lack of communication, weak development, and unprofessional handling of major changes led to the shutdown of multiple mining projects.
At the same time, new projects continue to emerge, and some established coins saw renewed interest. One of the most notable examples is Zcash. In 2025, ZEC attracted miners again as its price surged by nearly ten times compared to previous lows. This price growth made even older ASIC hardware profitable once more.
Remarkably, machines like the Antminer Z11 — originally released back in 2019 — returned to profitability thanks to improved market conditions. We will include a price and profitability chart here to illustrate this shift.
Despite all challenges, mining remains very much alive. It continues to reward those who stay informed, react quickly, and choose projects carefully.
Thank you for being with 2Miners throughout 2025. We wish you a Happy New Year, stable networks, strong uptime, and successful mining in 2026!
