The "old phone sitting in a drawer" case or what actually happens when you put it to work

This isn't a success story with big numbers. It's a realistic walkthrough of a scenario that probably applies to more people than they realize.

The setup: someone has an Android phone they replaced 1-2 years ago. It works fine. It sits in a drawer or gets used occasionally as a backup device. Battery is fine, Wi-Fi still works.

They install CT Browser on it, plug it into power, and let it run.

What they're actually getting:

The phone is running its CPU to contribute hashrate to the mining process. The output per device at this scale is small - that's not a secret and it's not a reason to misrepresent it. We're talking fractions of fractions over days and weeks.

Why it's still worth thinking about:

The phone is already bought. It's already consuming power when it charges. The marginal cost of running it this way is close to zero. The upside is accumulating Bitcoin over time without buying it.

For someone with no interest in trading, no exposure to crypto, and no hardware investment - this is a zero-risk way to build a small position.

What it's not:

It's not a path to significant income in the short term. If you're expecting to replace a paycheck, this isn't the mechanism for that.

Where it gets more interesting:

The referral network mechanic means that if others around you start doing the same thing, your aggregate output compounds. It's not a pyramid - you're not paying to participate. But it does mean the "old phone" scenario scales if you're the kind of person who actually gets people to try things.

Has anyone here done something like this with spare devices? Curious what the experience actually looked like over time.
