Just to many scammer around here. I guess we all have to learn it! I have to admit I fell for a scam once (gladly only lost about 200 bucks) but it was completely my fault. It was back when I started with cryptos and I had literally no clue about what I was doing. That is why I tell everybody new in crypto: DO YOUR OWN RESEARCH!

Many scams are obvious scams like the one you write about and literally everybody that knows the general basics about crypto will not fall for it. Sadly there are still to much people out there involved in the market with literally no clue.
