you can sell/buy bitcoin or be escrower.. is a work
you can buy with -3% bitcoin (for who sell fast) and sell +3% bitcoin (for who buy fast)
i think is good option
Yes i do that on localbitcoins, i buy bitcoins at -10% of the actual price and then sell it for more than 5% of the real price.
It is a good option, only that you must have a good reputation on there but it gives a lot of profit, since once you have a nice account everybody is gonna buy/sell to you.
But localbitcoins has too much fees for every deposit/withdraw, that is the only thing i dont like of those guys.
So i do it for a 15% profit from every operation 1: buy 2:sell them
