if a crypto user falls for this scam, then TBH, they really have no business using crypto, because they do not even understand the basics, hell their funds shouldn't even be stored in Gemini's platform in the first place.
You have no idea how naive some people can be. This is nothing, I was reading through the forum yesterday and I read a thread where a guy was attacked by a group of strangers in a parking lot because he went there to sell his USDT to a buyer he met online in Telegram which is the primary platform for scammers for privacy and security it provides.
Now, can you imagine how naive a person needs to be to trust someone they meet online and literally go to meet them in person to sell their cryptocurrencies?
The world is full of such people, sometimes you will find scams and scammers that are completely dumb and idiots, but guess what? They still find people they can scam because there is always someone more stupid than them. We live in a crazy world.
