CRUCIBLE turns spare GPU time into coin you keep — and gets out of the way the instant you need your machine back.
Because you should decide with real numbers, not a pitch.
Mining a graphics card converts electricity and the working life of your hardware into coin. On a 16 GB card that's well under a dollar a day, and at most power prices it will not cover itself.
CRUCIBLE is built for machines that are already running anyway — the desktop that idles all night, the box that's on regardless. It's a slow accumulation, not a paycheck. If you need money this month, this is the wrong program and we'd rather say so now.
What it's actually for: you're already burning the power. This decides whether that becomes heat, or becomes something you still hold in a year.
Every "mining wrecked my machine" story is the same story — software that takes what it can and never gives it back. CRUCIBLE has no such authority. It's supervised, and it yields.
Stops the moment you touch the keyboard, another program wants the GPU, or memory runs short. It waits its turn — it doesn't compete for one.
Hard temperature ceiling, and it won't restart until things have genuinely cooled — no flapping on and off at the threshold.
Full tilt while you're away, or a light background drip you'd never notice. Switch any time; nothing needs restarting.
Drop a file named STOP in the folder and mining halts within seconds, whatever the settings say.
Antivirus flags mining binaries on sight, honest ones included. So we ship none — you supply one you chose, and we check it hasn't been swapped before every launch.
It prints exactly what it's doing and where the coin goes, every single run. No telemetry, no accounts, no phoning home.
You keep the overwhelming majority. We take a small, stated share — and we never touch your side of it.
Your share is paid to your own wallet by the mining pool, directly. It never passes through us. There's nothing of yours for us to hold, forward, lose, or be trusted with — which is exactly how it should be.
The 5% is what funds CRUCIBLE and the First Digital Civilization. It's the price of the tool existing, and it's why it's free to run. You can raise it if you'd like to back us harder — plenty do.
Three steps. No account, no signup, no identity check — your wallet address is your account.
1. Put a miner you trust on the machine, and point CRUCIBLE at it.
2. Add your wallet address.
3. Choose drip or full, and start.
Your coins arrive from the pool. We are not in the middle.CRUCIBLE runs on Windows with an NVIDIA card. It reads its settings live — change the mode or your address while it's running and it picks them up on the next cycle.
