A friendly word of advice: read everything you can to educate yourself about stock trading. Your swimming in the most shark infested waters of trading in existence. Self education is a lot cheaper than what you stand to lose in pinks.
DONT INVEST ANYTHING YOU CAN'T AFFORD TO LIVE WITHOUT, NO MATTER HOW GOOD IT LOOKS!
Don't trust anything you read on "advice websites" without checking them out as many ways as you can. After all, who do you trust more, yourself, or some stranger on a web page?
Good luck in your investments, but be careful and remember to do your homework, "Due Diligence" (DD)
