Parts only wear out while the rig is running. When a part dies the rig switches off until you replace it.

Card	BTC / day*	Lasts	BTC over its life*

* Per single card, using the power supplies selected in the test rig. Shows whether your tier ladder holds up — better cards should earn faster and last longer.

Mod mechanics reference

A rig needs a motherboard, at least one power supply and one graphics card — and mains power — or it refuses to start.
All times are real running time: rigs only mine (and parts only wear) while switched on and powered.
The two PSU slots add together — two 50% units run a rig at 100% power. Weak PSUs slow every card in the rig.
Mined BTC spawns in the rig's storage. When storage is full, mining stalls until a player empties it — the "storage full after" time is your forced-interaction interval. A full rig banks at most 100 BTC of backlog; production beyond that is lost.
When a part is ruined the rig switches itself off; replacing the part and switching back on resumes, with all other parts keeping their wear.
Fuel is the hidden cost: the rig draws 0.14 energy/sec. One full vanilla generator tank runs one rig about 6h 37m (the generator burns fuel itself too). A generator has 4 sockets — every extra rig plugged in shortens the tank.
GPUs can be hot-swapped while the rig runs; the motherboard and PSU slots are locked until it's switched off.
An empty rig packs back into a portable kit using a screwdriver (costs the screwdriver some durability).

What this tool does

It edits the file your server reads to decide how fast rigs mine and how quickly parts wear out. You set two numbers per graphics card — how many hours it takes to mine one Bitcoin, and how many days it lasts — and everything else is worked out for you.

How mining actually works

A rig's output is every installed card added together, multiplied by the power its two supplies provide. So a rig at 50% power mines at half speed no matter how good the cards are, and adding a second power supply is the single biggest upgrade in the mod.

Rigs only mine, and parts only wear, while switched on and powered. All times here are real running time.

The two quick balancers

Set best full rig to earn N BTC/day — scales every card at once so your top rig hits that figure, keeping the tier ladder intact. Use this to set the ceiling of your economy.
Best PSU pair gives N% power — scales the power supplies. Card hours assume 100%, so pushing this above or below makes every rig faster or slower across the board.

Bitcoin item

Decides how coins stack, which sets how much a rig can hold before it fills up and stops mining. Non-stacking coins fill a rig at 50; stacks of 15 hold 750. Whatever you pick here must match your trader and types.xml.

Graphics Cards

Card	Time to mine 1 BTC (hours)	Wears out after (days)	BTC / day	BTC over its life

Per single card at full power (two top power supplies). Example: "7.5 hours to mine 1 BTC, wears out after 4 days" → that card earns 3.2 BTC a day and about 12.8 BTC before it dies.

Power Supplies

Power supply	Power % (each)	Wears out after

The two PSU slots add together — two 50% units run the rig at 100% power.

Loot spawns (types.xml) — optional

Generates loot entries whose rarity matches your production balance — the better a part mines, the rarer it spawns. Recalculated live from the rates you set above. Includes persistence entries (rig, kit, BTC) so deployed rigs and stored coins don't despawn.

Preview the generated XML

Install: put the file in your mission folder (e.g. mpmissions\dayzOffline.chernarusplus\ddtb_miningrig\types.xml) and register it in cfgeconomycore.xml:
<ce folder="ddtb_miningrig"><file name="types.xml" type="types"/></ce>
Numbers are a starting point — tune totals to your map and player count. Unchecked legacy parts still get no-spawn entries so existing ones keep persisting.

Drop it in $profile:DDTB_MININGRIG\Config\ and restart your server.

Review — what changed & the exact JSON that gets exported

Changes vs mod defaults

Config file (JSON)

Deploy & verify — install steps and troubleshooting

First deploy? Turn on Log mining and Log decay in the settings row before exporting, so you can verify it works.
Back up your current config, then place the downloaded file at
<ServerProfile>\DDTB_MININGRIG\Config\DDTBMiningRigConfig.json
Restart the server. The config is read once at startup.
Power a rig on in game and watch <ServerProfile>\DDTB_MININGRIG\Logs\MININGRIG_*.log — GetSatoshiMined lines mean mining is working, health lines mean decay is working.
Something off? Config not loading → JSON error; delete the file and restart to regenerate defaults, then re-import here. No BTC → rig not powered, or a classname is missing (see Checks above). No wear → "Parts wear out" is off.
