You didn't tell us if it was a bitcoin trading or other way of investments such as the fiats. But all I can say about this is that don't trust any given site either already compensating you with interests of your investment or any format claiming to give you investments returns of profits.
Don't be so easy to be romanced and fooled with sugarcoated words with some sorts of attractive promises or reviews via internet researches. There are local and international scammers who operates cordially according to by they could deliver their illegal jobs.
Stay of from Ponzi schemes. They're strategic scammers. Let's me warned.
