6. The betrayed scammed. Whether a beginner or an expert, the betrayed scammed has trusted someone (friend, colleague, lover...) and lost his or her funds.
Yes I have been scammed by such a person. It was about an account that I agreed buy. He seem like such a nice person. You can't even tell apart if he is a scammer. So like out agreement I send him the fund. Then he said some work had to be done. So I needed to wait. I though it was okey because it was late at night. The next day I texted him he said he was several ill. Then I finally understood I was scammed. I tried calling him many time he didn't received. In the end he blocked me from both social accounts and my number.
The clipboard virus happened to me recently. Someone I didn't know texted me in telegram and gave a file. I thought it was a normal file. I wasn't that caution that time so I opened it and everything was fine.
I think you missed Ransomeware virus scam. I was a victim of it. All of my data got encrypted due to this malware and I couldn't decrypt my data due to it was a new kind of malware. Luckily all of my data, wallets, key, passphrase were stored in the cloud. So I got saved a big time that time.
So as I victim my advice never install anything if it isn't from a trusted source.
