Honestly, I'm going to say to you is that it's critical that you conduct broad market study to figure out which option is ideal for you. This will enable you to test your business acumen to the fullest.At present in my country, perhaps the same in the whole world, the sales of computers have decreased due to their high cost. The vast majority of people choose to repair the PC and upgrade it, because the cost is less than buying a new one. My cousin is suggesting that she start a sales business, but I'm trying to convince her that repair and repower is more profitable. Which of the two options is better?
