1) You should register yourself at the game Happyminer.Com and start a gold mining process or buy an already registered account with some gold value inside. For example one can buy Happy miner's account at the online game accounts trading auction Virtaex.Com
2) Continue the gold mining process for some days/weeks. Its a very easy process. Your miners are mining gold. You can buy some miners to make it faster using some gold value.
3) Sell the account after the gold value increased. For example one can sell Happy miner's account at the online game accounts trading auction Virtaex.Com
The margin between price at the step 1) and the step 3) is your profit
