Yes, I have been scammed once for $5,000. I was paying from my Ledger Hardware Wallet to Exchange for a quick P2P Withdraw and I realized I sent it to some address which has exactly same first 5 characters and last 5 characters similar to my Exchange Deposit Address. The attack which was done on me was Address Poisoning. I just copied the address from my Recent Transaction History on Ledger and sent $5k USDT. I still feel ashamed of that as I have kept myself safe from every other possible scam attack.
It's okay to feel ashamed for encountering such a costly mistake at the brief period it happened, but you don't have to beat yourself up about it for long and being ashamed till now. Every human is prone to mistake and we have at different times in life made our different mistakes of different degrees but we just don't have to live with it. So mate let the shame go away mistake is part of life and no one is above it, we can only try not to repeat it and am sure you're doing that.

3. Greedy scammed. Those who were promised crazy returns without doing anything. (Bitconnect for example or Madoff in TradFi))
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.
Has this happened to you or someone you know ?
I have had a direct experience with number 3 but as for number 6 it was a friend that fell for that in his early stage in cryptocurrency.
I got involved with some virtual mining stuff like that, where i had to pay money to purchase a crypto mining machine in the platform which will be mining coins for me every day and eligible to withdraw the coins to my wallet at each end of the month. It was a funny experience actually as I had to always checking the platform first thing eaxh morning I wake up to see how my investment was going. Long story short, I woke up one morning after two weeks of investing into it only to get a massage that the site is doing an upgrade and we should wait for update very soon, for over more than 3 years now am still waiting for the damn update about the site upgrade. Lol.
That was how I lost my money to that virtual mining scam.
As for the number 6, it happened to a friend who trusted another friend of his to buy him bitcoin into his wallet, just for his friend to
buy below the amount he gave him money for and sent to his wallet, at that time this my very friend don't know how to calculate bitcoin or convert it to usdt because he was just trying to learn about crypto from the very person that was scamming him. It was after some months he got to know he was shortchanged in the amount of bitcoin his so-called friend sent to his wallet.
How awful.
