How can I get some profits of this? I can buy BTC for 5 minutes, next to my house they sell it. Any ideas?
You didn't give enough details, but If I understood right, you want to buy them near your house (an ATM or from someone) and sell them later. The rule is to buy low and sell high and in order to make a decent profit, you will need to buy large amounts so basically, just take a look at the fees and do the math.
