Would raspberry pi make a good trading computer?

[beamin]

I have two extra computer screens and I want each one to show and exchange on it all day everyday. Not sure if I would trade on them but want screens in my bedroom that are always on my coins since I hate missing out. Although I did just catch a good buy from the dip that started this afternoon. But I saw it around noon and kept watching it for 14 hours.

Are the pis secure if you want to trade on them? As I get more serious into this I want dedicated computers that do just coins and the email for them. No porn no anything else that could compromise them. "work" computers I call them. Having two lap tops is a pain.
