Machine Specifications & CapEx

Quarterly BTC Production (declining with difficulty)

BTC mined per quarter drops each quarter as difficulty rises. Halving cuts reward 50%.

Breakeven Month Comparison — All Scenarios

Lower bars = faster payback. Electricity = $0. Structure (+10%) included in CapEx.

Hold-to-Halving vs Sell-Immediately

All coins mined before halving — value if held at scenario price vs sold at today's BTC price.

♻ Compound Reinvestment Strategy

Farm starts with 25% of total CapEx deployed. Each quarter the full USD yield is reinvested to buy more machines until maximum farm power is reached. New machines earn from the next quarter. Fully cumulative.

Summary at Halving Day

Initial investment = 25% of full CapEx. Reinvestment uses quarterly USD yield to buy TH at cost+10% structure. Capped at max farm power. Final coin value at each scenario's BTC price.
