## What it is
No Coin is a small browser extension for Chrome, Firefox, and Opera that blocks browser-based coin miners such as Coinhive by blacklisting known mining domains. It lets users pause/unpause blocking so they can opt in to legitimate mining like proof-of-work captchas.

## Use cases
- block coin miners like coinhive in my browser
- stop websites from using my cpu for crypto mining
- prevent cryptojacking while browsing
- allow mining scripts temporarily to pass a captcha
- block browser mining without a full adblocker

## When to choose
- you need a lightweight, dedicated miner blocker separate from your adblocker
- you want fine-grained pause/unpause control over mining scripts

## When to avoid
- you use a modern browser with built-in mining protection
- you already run an adblocker with an up-to-date nocoin blocklist
- you need actively maintained software

## Facets
- artifact type: plugin
- maturity: abandoned
- function: security, privacy
- domain: security, privacy, browser-extensions
- platform: browser, browser-extension
- tags: coin-miner-blocking, cryptojacking-protection, adblocker, discontinued, cryptocurrency
