Fraud.

I have been participating in CFD trading for over 2 months on this platform i made 126,683$ with my 49k investment capital. One time early when I first started I withdrew $1000 usdt to my Coinbase wallet without any problems. The site told me operation was successful.Then approximately 3 days later they inform me that due to the rules of their platform and the IRS I'd have to pay 20% on my earnings before I could withdraw my money.
