Warning: It is highly likely that Lootbits.io is utilizing its users' machines resources to mine cryptocurrencies without their consent or knowledge.
I reached that conclusion based on my experience, because every time I visit that shady website my laptop works at full speed and sometimes overheats. and when I close it everything goes back to normal.
It's not my laptop. I have a decent one. and that doesn't happen with other websites. Even if I open dozens of tabs it doesn't happen. only when I visit Lootbits.io
The mining process gets activated when you click on the popup messages they show you whenever you do anything on their website (for example: when you claim your free gems).
Don't break your machine.
STAY AWAY FROM THAT WEBSITE!
I don't think they are mining but the high load is because of too many ads as this happen with me whenever I use a site that have a high number of ads.
