Antminer L9 vs S19 XP Hydro 295T – What’s the best pick over the next 1-1.5 years?
Hey everyone,
I’m currently planning a mining setup to deploy over the next 1 to 1.5 years.
My Setup & Constraints:
Electricity: Solar power plant no cost
Power Supply: 63A panel (~25 kW total capacity on 3-phase, or ~14.5 kW on single-phase).
Because operational costs are zero, my decision comes down strictly to capital expenditure, daily yield, and long-term accumulation over a 12 to 24 month horizon.
I’m weighing two specific deployment options that max out my available power:
Option A: 8x Antminer L9 (Scrypt - LTC / DOGE / BEL)
Total Hashrate: ~132 GH/s – 140 GH/s total
Power Draw: ~27.2 kW total (~3,400W per unit)
Hardware Cost: ~$16,800 ($2,100 per unit)
Strategy: Mine Scrypt (merged mining DOGE + LTC + BEL) to build a massive stack before any potential market expansion. Air-cooled, plug-and-play setup.
Option B: 4x Overclocked Antminer S19 XP Hydro 295T (SHA-256 - Bitcoin)
Total Hashrate: ~1.3 to 1.4 EH/s (1,300–1,400 TH/s total) via custom firmware tuning/overclocking (~330–350 TH/s per unit).
Power Draw: ~24 to 26 kW total (~6,000W–6,500W per overclocked unit).
Hardware Cost: ~$4,400 ($1,100 per unit) + dry cooler/hydro container infrastructure costs.
Strategy: Max out raw BTC terahashes. Cheaper upfront hardware cost with massive Bitcoin accumulation, but requires managing a hydro cooling loop.
The Questions for You:
ROI & Yield: At $0 electricity, does 1.3+ EH/s of raw overclocked BTC hydro power outperform 8x L9s on Scrypt over a 12–18 month horizon?
CapEx: Option B saves over $10k on hardware costs compared to Option A. Is it smarter to put that saved $10k directly into buying spot BTC/DOGE, or should I re-invest it into more miners?
Infrastructure & Reliability: How reliable is pushing 4x Hydro units at 6kW+ each on a 63A connection compared to the simplicity of running air-cooled L9s?
Given $0 power and a 63A limit, which setup would you choose for maximum return over the next 1-2 years?
Looking forward to hearing your insights!
