Do some research on how sketchy some of the big players in the exchange scene are. Look at the "hack" that happened at Bitfinex. Can anyone cash out USD from there? Try and find out who owns Poloniex or where they operate out of. Check out how Bittrex only lists a storefront in a half abandoned strip mall in Las Vegas as their location, and how much the coins traded on that platform have increased in price recently.
How much do you trust a business that won't list a phone number or physical address? And there's no information on who owns or operates the business? And there's no information on how they are licensed to operate? And there's no details on if or how customer funds are held segregated from operating funds?

Don't let greed overcome your better judgement.
