It's alarming to see that others would even go that far just to get easy money. As long as money is involved, your security will always be at risk. That is why it is best to be anonymous and be silent if you are a crypto bag holder. Most people I know in our country have their pseudo names and pseudo profiles on social media to protect their identity.
The reason why such attack happens is when, someone knows, or you publicly/ or even online announce that you are involved, holding, earning a lot on crypto. Always protect your identity.
