OP, are you actually the guy referred to in that Tweet? Or are you just sharing this?
Could you please clarify what happened, and what site it is about? I ask you this to protect others who may become victims of the same scammer and that we can report that site to Google as phisning.
If I got it right from the post, your got your Ledger only recently, and you only lost that altcoin mentioned in tweet. But I see it is a more substantial amount, so I'm sorry for your loss.
From this quote alone: "
When I need some help I started to google and ended up at a false telegram chat where I was linked to a site where I unfortunately without thinking gave them my information"
I'm guessing the victim had a certain problem with his/ledger, did a Google search concerning the problem, downloaded a fraudulent software, and entered in his/her wallet's mnemonic phrase. I guess it's a safe assumption as probably 90% of the cases are like this.
