Heard about BTC few years back, through some of my peers and was quite not sure about investing because I was not quite sure about it. But I did invest and didn't expect my profits to increase just like that. Worth investing in BTC just use the site with best rates and secure when exchanging.

For almost 2 years into Bitcoin this is one of the sites I find that offer best rates for buying and selling bitcoins. Also, I give their customer service a 5 star for helping me around when I bought first time.
