I know a lot of people who fell victim to these scam ponzi companies that parade themselves as cryptocurrencies investment platforms. About 3 of my good friends got scammed from the ones that they saw on Facebook and invested in them, only for them to vanish all of a sudden.Ponzi scheme investment scams have occurred everywhere, both offline and online, Several years ago I was also tricked online and my money disappeared, recently my colleague, (when the price of Bitcoin was $ 20k) invested fiat money (offline) to buy Bitcoin , and was kept by the investment company, but only a few months the company without the license disappeared.
