Unable to withdraw

I was lured inside a gay chat to a nice person that seems to have found a method for earning more money from a platform called guotai https://m-en.wentaijiaoyu.com/Thanks to his suggestion I can easily gain money, the first time withdraw was easy, the next time, withdraw was difficult and once I put a lot of money into, withdraw became impossible they always ask for more taxes and money .Easy money don't exist!
