You had your best shot at converting them last year, when they were ignorant, and hadn't lost $10,000+ on it yet. Today, they're going to be mad at their losses, the lies, and the fraud, and the outright stealing / locking of accounts.
The people in category #2 are almost certainly, permanently, lost. You can't just play with people's savings like this and expect them to trust you.

This isn't like a "normal cryptocoin crash". Celsius, and now Gemini, account holders are unable to withdraw funds. Who knows how far this financial-contagion will spread?
What's going on right now is a fundamental loss-of-trust.
The price goes up, the price goes down. That's not the important bit. Locking down accounts and destroying goodwill is the problem with this crash.
