Cryptocurrency mining no longer needs to be dominated by giant ASIC rigs and massive power bills. My setup uses four Raspberry Pi miners running Yescrypt CPU mining, combined with several NMMiners (USB SHA-256 miners) on Zpool, all auto-converting rewards into Ravencoin (RVN).

This system is built for:

• Low cost

• Low power

• High uptime

• Slow and steady RVN accumulation

Below is the full breakdown.

1. Hardware Overview

Raspberry Pi CPU Miners

Device	Model	Miner	Algo	Pool	Output
Pi #1	Pi 5	cpuminer-opt	Yescrypt	Zpool	RVN via auto-convert
Pi #2	Pi 5	cpuminer-opt	Yescrypt	Zpool	RVN via auto-convert
Pi #3	Pi 4	cpuminer-opt	Yescrypt	Zpool	RVN via auto-convert
Pi #4	Pi 3	cpuminer-opt	Yescrypt	Zpool	RVN via auto-convert

All Pis run Yescrypt because it is the most efficient CPU-friendly algorithm for low-watt hardware.

NMMiners (USB SHA-256 Miners)

• Hashrate per unit: 300–350 KH/s

• Power usage: ~5–7 watts each

• Pool: Zpool

• Output: RVN via auto-convert

Combined, they add nearly 1 MH/s of SHA-256 hashing into the same RVN pool.

2. Why Mine Yescrypt on a Pi?

Efficiency per Watt

Pi Model	Hashrate (Yescrypt)	Power Draw	Efficiency
Pi 5	2.4–3.1 KH/s	10–14W	~0.22 KH/s per watt
Pi 4	1.4–2.1 KH/s	7–8W	~0.20 KH/s per watt
Pi 3	0.8–1.3 KH/s	6–7W	~0.16 KH/s per watt

Total Combined Hashrate

All Pis together:
≈ 6–8.5 KH/s Yescrypt

This is extremely efficient considering the small power footprint.

3. Why Convert Everything to Ravencoin (RVN)?

Zpool lets you mine any algorithm and get paid in any supported coin. That means:

• Mine Yescrypt (CPU-friendly)

• Mine SHA-256 with NMMiners

• Get all rewards converted into RVN

Why RVN?

1. Lower difficulty than BTC/BCH → easier to accumulate

2. High liquidity on multiple exchanges

3. Strong long-term fundamentals

4. Perfect for low-power, slow accumulation mining

4. NMMiners: Extra Hashpower for the Same Goal

NMMiners aren’t strong enough to chase Bitcoin, but they shine on Zpool:

• They submit constant low-diff shares

• Zpool converts those shares into RVN

• Their watt usage is microscopic

Expected Output

Metric	Value
Total SHA-256 Hashrate	~900 KH/s – 1.05 MH/s
Daily Shares	240–320 per hour combined
Expected RVN/day	0.25–1.1 RVN

Even as “tiny miners,” they still contribute meaningfully because Zpool smooths the payouts.

5. Combined Daily RVN Estimate

Taking into account:

• Yescrypt difficulty

• Zpool profitability rotation

• SHA-256 share contribution

• RVN market price fluctuations

Your realistic RVN accumulation looks like:

RVN Per Day Estimates

• Low: 0.4 RVN/day

• Normal: 0.8–1.5 RVN/day

• High volatility: 2–3 RVN/day

This is achieved with under 40 total watts of hardware.

6. Why This Setup Works Financially

1. Ultra-Low Power

Most of the system:

• Runs on small USB chargers

• Can run off a battery bank or solar

• Costs almost nothing to maintain

2. Mine Where CPUs Perform Best

Yescrypt is one of the last CPU-friendly profitable algos.

3. Auto-Conversion Maximizes Profit

You don’t chase algorithms;
Zpool does it for you.

4. Multiple Small Miners → One Strong Reward Stream

The Pis + NMMiners produce a constant drip of shares that accumulate into RVN.

5. Perfect for Long-Term Stacking

Even small daily amounts become massive if RVN rises:

• $0.02 → $0.20 → $2.00+ potential
