Celsius payout and Hyperwallet

Hello ! So I got an email after 4 years holding this piecebof crap that is Celsius bankruptcy and they sent me an email about me getting back my BTC that I got locked out years ago.

Now question is that they ask for my phone number etc and I want to know : how do I know it's a scam or not and what précautions should I take.

Because I don't want to be double scammed right know

What is the best way for me to get out of celsius and hopefully get my money back and also know it is not a bloody scam that they got my email through dara l'eau or something.

Has anyone gotten payout and how is hyperwallet safe?
