Friend lost $600K in BTC scam

My mom just told me this story. We have a family friend we’ve known since 1990. He put 1/3 of his life savings in BTC. I’m not sure of the exact details but he put money into a crypto account and somehow his account got hacked and he’s out $600K. He’s been freaking out over the past few weeks because it was his kids college fund and also his personal retirement fund. This is just a reminder to everyone to be really careful with these types of investments. I know there is a lot of money being thrown into crypto and it will attract all the wrong types of attention. Keep your account locked down. Don’t answer phone calls or any messages at all about your account. Stay vigilant.
