I don't think you understood the OP. I'm just wondering if this is a common thing or not. I'm not questioning whether or not to "use the wallet". Many people scrape Pastebin for user/passwords that may be accidentally posted. I saw this get posted and was surprised when the user/pass actually worked and claimed to be a BTC wallet. I've never seen this SSH wallet scam before and couldn't find anything on the web about it which is why I posted it.
Yes, this is extremely common, and the oldest trick in the book. Make people think they have somehow lucked or won money, and then ask them for a fee before they can withdraw it.
You see it everywhere, Bitcoins, virtual items (think csgo, other ecash stuff), usually this is done through something like you posted, where the user thinks he has "stumbled" or "lucked" on a large sum of money, while in reality, it was infact all planted and or rigged.
You just stumbled upon a slight variation of this scam where they planted an SSH combo to a server that supposedly "hosts" a bitcoin wallet with 2.7
BTC, but of course, before you can "withdraw" it, you need to deposit money first.
It's all the same scam.
