Can You Mine Crypto on a VPS?

Why providers ban mining

The ban isn't ideological — it's operational. Mining creates specific problems for shared VPS infrastructure:

• CPU starvation. Proof-of-Work mining pins CPU at 100% continuously, 24/7. On shared infrastructure where 20-50 VPS instances share the same physical CPU, one mining customer degrades performance for every other customer on the node. Providers sell shared CPU on the assumption that most customers use it in bursts, not continuously.
• Electricity cost. VPS pricing assumes average CPU utilization of 5-15%. Mining pushes utilization to 100%, which means the electricity cost of running that VPS exceeds the revenue the provider collects from it. The customer is arbitraging cheap VPS pricing against electricity costs — the provider loses money on every mining customer.
• Hardware wear. Sustained 100% CPU load generates heat that accelerates component degradation. Fans run at maximum speed. Enterprise SSDs have write endurance ratings that mining workloads approach faster than normal use.
• Abuse pipeline. Many mining operations use stolen credit cards or compromised accounts to provision VPS instances for mining. Providers see mining as correlated with fraud, which increases their abuse processing costs.

Provider policy map

Here's what each major provider's AUP actually says about cryptocurrency mining, with direct quotes where available:

"Banned" means the AUP explicitly prohibits mining. "Silent" means mining isn't mentioned — which is not the same as "allowed." Providers with no explicit policy can still terminate your account under general "excessive resource usage" or "service disruption" clauses.

The Hetzner-Solana incident

In November 2022, Hetzner enforced their mining ban against Solana validators in a single coordinated action. The numbers were staggering: over 1,000 Solana validator nodes were terminated, representing roughly 20% of the network's stake-weighted validators. The Solana network continued operating — it's designed for node churn — but the incident exposed how concentrated Solana's infrastructure was on a single hosting provider.

The significance wasn't just the scale. It was what Solana validators were running: Proof-of-Stake validation, not Proof-of-Work mining. PoS validation uses moderate CPU (nothing like PoW mining) and was arguably a legitimate server workload. But Hetzner's policy draws no distinction — all cryptocurrency-related operations are prohibited, regardless of CPU impact.

The Solana community's response was to diversify hosting away from any single provider. But the lesson for individual users is simpler: Hetzner means it. If your workload involves cryptocurrency in any form — mining, validating, running a node — Hetzner will find it and terminate it.

PoW vs PoS — providers don't always distinguish

Proof-of-Work mining (Bitcoin, Monero, Litecoin) and Proof-of-Stake validation (Ethereum, Solana, Cardano) are fundamentally different workloads:

From a provider's perspective, PoW mining is straightforward to ban — it's an abuse of shared resources. PoS validation is more nuanced. A Solana validator uses CPU more intensively than a typical web server but less than video transcoding or machine learning training. Yet Hetzner bans both. Other providers (DigitalOcean, Vultr) prohibit "mining" without clarifying whether PoS validation counts.

If you're running a PoS validator, don't assume you're safe just because your CPU usage is moderate. Read the specific AUP language. If it says "cryptocurrency" broadly, not just "mining" specifically, PoS validation is within the ban.

How they detect it

Providers don't manually inspect your VPS. Detection is automated through several methods:

• CPU pattern monitoring. Sustained 100% CPU utilization over hours or days triggers alerts. PoW mining has a distinctive pattern: constant maximum usage with no variation, unlike web servers or databases which spike and drop.
• Process name scanning. Known mining software process names (xmrig, ethminer, cgminer, bfgminer, nicehash) appear in process lists that providers can inspect. Renaming the binary is trivial but doesn't fool deeper analysis.
• Network traffic analysis. Connections to known mining pool IP addresses and domains are flagged. Mining protocols have recognizable traffic patterns (Stratum protocol on specific ports).
• Community reports. Other customers on the same node notice degraded performance and report it. Provider support investigates and finds the mining process.

Detection typically leads to a warning email with 24-48 hours to comply, followed by suspension. Some providers (Hetzner, OVH) have suspended without warning. Data is usually preserved for a retrieval window, but don't count on it.

Where you actually can mine

Mining on a shared VPS is economically irrational regardless of policy — the VPS cost exceeds mining revenue for any coin on CPU. But if you're running a PoS validator or blockchain node, your options are:

Dedicated servers (bare metal)

Some providers that ban mining on VPS allow it (or tolerate it) on dedicated servers where you're the only tenant. Contabo's dedicated servers may allow mining workloads not permitted on their VPS. OVHcloud's bare-metal range has different terms than their VPS/cloud products. Always verify the specific terms for the product type you're buying.

Crypto-friendly providers

A small number of providers market specifically to blockchain workloads. These tend to be smaller, niche operations with higher prices. Search for "blockchain hosting" or "validator hosting" rather than generic VPS providers. The Solana and Ethereum communities maintain lists of validator-friendly hosting.

Colocation

Bring your own hardware to a data center. You own the machine, the data center provides power, cooling, and network. No AUP restrictions on what you run because it's your hardware. This is the path for serious mining or validation operations.
