Understand everything, straight to the point
Guides, definitions and answers sorted by topic. Our stance: transparency, never promised gains.
What we do not promise
× No promised gains
Mining depends on parameters that change (market, difficulty, costs).
× No guaranteed yield
No guaranteed ROI or performance. Reliable and transparent operations.
× No black box

01 / Understanding mining
Mining secures the Bitcoin network. Specialised machines (ASICs) solve cryptographic calculations and are rewarded in BTC. In practice: you turn electricity and computing power into Bitcoin.
An ASIC is a machine designed solely to mine a given algorithm (e.g. SHA-256 for Bitcoin). Far more efficient than a PC or a graphics card.
Hashrate (TH/s) measures computing power. Consumption (W) measures energy. Efficiency (J/TH) combines the two: the lower it is, the more profitable the miner is for the same energy.
A pool combines the power of many miners to smooth out rewards. The production data you see comes directly from the pool, read-only.
02 / Buying & owning
Yes, 100%. blobb hosts and operates them; you can retrieve or resell them at any time.
We source, receive and install your miners at our sites. Fast go-live (often 48-72h once received). You track everything via the dashboard.
Yes. The machine belongs to you; you can resell it (second-hand market) or ask us for a buyback subject to availability.
03 / Hosting & costs
You pay for electricity based on actual consumption (from ~0.05 €/kWh depending on the site) plus operations (maintenance, monitoring). Everything is detailed in the contract, with no hidden costs.
In our secure sites: Iceland, Finland, United States, Kazakhstan. Each site shows its kWh price, its energy mix and its availability on the Hosting page.
We aim for 99% uptime. 24/7 monitoring and maintenance are included; covered interventions are handled by our teams.
04 / Profitability & taxation
Estimated revenue (hashrate x BTC price x network parameters) minus the electricity cost. Our simulator shows both favourable AND unfavourable scenarios.
No. It depends on the BTC price, network difficulty and energy costs. We do not promise any financial outcome.
The treatment depends on your structure (individual or company: depreciation of the equipment, operating expenses). We point you towards best practices, without replacing personalised tax advice.
It mainly depends on your electricity cost and the miner's efficiency. It is a long-term strategy: our simulator helps you decide with full knowledge of the facts.
05 / Warranties & support
Manufacturer warranty + dedicated support. The miners are checked before shipping. Covered interventions are handled by our teams.
24/7 monitoring detects incidents; maintenance is handled without any action on your part. Any downtime is transparent in your reporting.
The risks, frankly
Bitcoin price volatility, rising network difficulty, gradual hardware obsolescence: profitability is never guaranteed. Mining is a long-term industrial strategy, not a shortcut to quick gains.
