You should be Happy.
Because you just lost $170.
One of my friend who was doing SEO for a living started Options Trading and first he took some money as a loan from other people and rest was leveraged margin calls. 6 months later he sold his house and moved with his parents.
3 months later I heard he sold his car and purchased a new moped.
Last month I heard he is still driving that moped but now he has to pay 80,000 USD to people who have loaned him money.
He met me 15 days ago and wanted me to invest 20,000 USD and said he can give me 50,000 in a month. LOL.
I think you should be happy you just lost $170.
