How does cloud mining work on HASHCLUSTER?+
HASHCLUSTER allocates GPU resources from our distributed datacenter clusters to your mining session. You select a cryptocurrency and cluster power level, and our infrastructure handles the rest. No hardware or software installation required — everything runs in the cloud.
Does mining use my device's resources?+
No. Your phone, laptop, or PC is not used for any computational work. All mining is performed entirely on our remote datacenter GPU clusters. Your device simply displays the session dashboard — it won't heat up, slow down, or drain battery any more than browsing a regular website.
Why is there an infrastructure fee?+
Mining requires significant computational power. The infrastructure fee covers GPU cluster operation costs, electricity, cooling, and network maintenance across our datacenters. The fee percentage varies based on the cluster power level you choose (8%–11%).
Is there a minimum fee?+
Yes, the minimum infrastructure fee is $70. If your calculated fee based on the percentage is less than $70, the minimum applies. This covers the base cost of allocating cluster resources for your session.
Why do you store data only in localStorage?+
Privacy is our core principle. By storing all session data exclusively in your browser's localStorage, we ensure zero server-side tracking. No accounts, no KYC, no cookies, no analytics. You control your data completely — clear your browser storage and it's gone forever.
What happens if I close the browser during mining?+
Your session is automatically paused when the tab becomes inactive or the browser is minimized. When you return, the session resumes from where it left off. Your progress is saved locally, so you won't lose any mined earnings.
How long is a mining session?+
Each mining session can run for up to 20 minutes. You can stop the session at any time before the limit. The session timer only counts active time — it pauses when you switch tabs or minimize the window.
What is a session code?+
Each mining session is assigned a unique code (e.g. HC-A7K3-P9BW). This code identifies your session for payment processing. If you leave the site before paying the infrastructure fee, you can return later and use the session code to complete your withdrawal.
Which cryptocurrencies can I mine?+
We support 10+ cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Toncoin (TON), Monero (XMR), Dogecoin (DOGE), TRON (TRX), Cardano (ADA), Polkadot (DOT), Tether (USDT), USD Coin (USDC), Litecoin (LTC), and Ripple (XRP).
How do I receive my mined crypto?+
After stopping your mining session, you'll be asked to enter your wallet address. Once you pay the infrastructure fee via deposit or WalletConnect, your mined earnings are automatically sent to your specified wallet within 2 network confirmations.
