That has nothing to do with crypto and everything to do with this fake exchange scam, and even with a real exchange it has to do with consumer education on using non custodial apps
It’s downright weird that you have this other mental category for things that say crypto where your mental processing power throttled to the conclusion is “its crypto so let me blame the victim instead and ignore who chose to create a victim while they sent her death threats on whatsapp”
Obviously it sucks for the lady, but to some extend it certainly deserves a financial darwin award.
That sector has plenty of things that follow the expected social contract of all parties, which can and does support balances of $4 million and far higher.
Your unwillingness to see that is not really a productive conversation here, although you’re in like company right now on this forum, you shouldn't be.
¯\_(ツ)_/¯
