I trade and buy some altcoin then sell. I get a sizable advantage. I allocate 0.5 Bitcoin to buy altcoin each week. profits of about 50%. I suggest you play the trading if you want to get rich. This is very easy, you just have to look at the statistics properly and carefully.
If you have your own business you will work with more energy and more dedication as you know that you are working for yourself and not for any shit company who doesn't care how hard you work for them how big revenue you generate for them. So it is better to work for ourselves and earn more money. And you also have feeling of being the boss and you are the king when you have your own business.
