Hello
I keep getting e-mails from Bitcoin asking me to invest, but yet I keep reading reviews saying it is one big con.

Emails from who? What reviews? You should know that you're asking the opinion of people who frequent a forum
dedicated for Bitcoin. You will only ever get positive responses here, except from the few who are only here to troll and/or spread FUD.
That being said, I would advise you to do your own research. You should never invest into anything you know nothing about, and I assume that is true for you. Check out the fundamentals, and you would be able to paint your own picture as to whether Bitcoin is a con or not. (Protip: it's not) Either way, you should keep in mind that no investment is completely safe, and that by investing, you're taking on risks.
Also: watch out for the emails you have been getting. If you ever decide to buy, it would be far safer to visit an official exchange. The email could be a phishing attempt.
