Hi all, I am looking for advice please....is it worth buying btc at a lower rate on sites like localbitcoins.com and selling them on at a higher rate? Is it worth doing and is there actually money to be made from doing this please? Any advice greatly appreciated, thanks 
Just like everyone do on forex, trading on bitcoin also another same case. If you are good on analyze the market prize, buy when the price on lowest point. And here's the different between trading on forex and bitcoin,IMO : mostly bitcoin market's graph provide unstable chart, so it's more difficult to guessing when the price reach highest point. At least in called the risk, without the risk, everyone can be a winner.
