Mind you, this is over a period of more than 2 years, so it isn't that bad.
I just make sure never to gamble more than I can afford.
Not only for new investors but also for veterans and pro investors , all of them should only invest funds that they can afford to loose . confident can surely attract luck but it does not strike at all times therfor you still must be careful when playing a gambling game . better if you can only set a limit ( e.g stop at a win , or stop a loss ) in that way , you can minimize your losses while maximizing your profit at the same time .
