So I was spending my free day free, and got a DM from a sketchy discord bot named Nexus Bot, which claimed that I won 0.2 BTC and I won't need to do anything else, but redeem my promo code and withdraw my winnings. Unfortunately and obviously, it was a scam. When I registered to the site, I found out that I am required to deposit 0.015 BTC to a site that even Google can't find. When contacted support, was told that it's a system against money laundering and that was, obviously, said in a very Indian-ish English language, which didn't really make any sense - took me a few minutes to realize what was said to me. Nexus-Wallet.com seems to be an absolute scam.
