After I deposit btc to Valhalla, I can't login to my account. Although I'm sure my username and my password, it says they're wrong. No answer from support and reddit moderators for 24h. When I open topic on Valhalla subreddit, I see that several people have that issue, one of them can't get any answer from support for 4 days. Think twice when you deposit money to Valhalla; looking exit scam although it still on superlist.
did you even read the warnings about them on the superlist https://www.reddit.com/r/darknetmarkets/wiki/superlist#wiki_valhalla_.28former_silkkitie.29
