The financial part of this scam begins when users try to cash out any “winnings.” At that point, the gaming site will reject the request and prompt the user to make a “verification deposit” of cryptocurrency — typically around $100 — before any money can be distributed. Those who deposit cryptocurrency funds are soon asked for additional payments.

In many ways, these scambling sites borrow from the playbook of “pig butchering” schemes, a rampant and far more elaborate crime in which people are gradually lured by flirtatious strangers online into investing in fraudulent cryptocurrency trading platforms.

Unfortunately it still works.
