Bitminer.io says that it's browser miner works for "free", which should be understood as "scam" in general. So even if you want to try this (don't), just wait half a day because then I can check if they allow withdrawals.
My laptop is running this website. I went to the website and clicked on the mining button. Few minutes in and the satoshis are piling up...
Can you mine via browser without a script, or without anything at all running in the background? WebRTC is disabled, all scripts/flash/etc are disabled. Disabled in the browser options and by extensions to prevent WebRTC leakage (WebRTC Control) and block all scripts in general (uBlock and Antiminer).
Tasklist however says it uses 4,7% of my GPU at the moment.
Anyone with a better understanding of this who can enlighten me ^^ ?
