Thanks all for your answers, I'm afraid you're all right

probably a scam, well 99.9% sure (let's give a 0.1% for hope

)
I'll try to get in contact with Wert.io anyways to get some info even if it's probably a lost cause.
There is many more lookalike coins on best walllet, I didn't know this wallet before buying bitcoin hyper but it's the wallet they advertise on their page so I donwloaded the app. It's pretty scarry how many scammers there is on crypto market, well it's not my first day on internet and I should have been more carefull before buying this crap. You always learn your lessons by failing

I'll try to keep you inform if I get some answers from Wert.
Thanks for your help all
