When you ask someone for advise they always say buy low and sell high but this is very tough.
What is your strategy for buying low and selling high?
Do you agree with buy low and sell high is very tough?
Well since that is the means by which truly it is however. You purchase when the esteem is low, hold it until the point when the esteem rises and after that that is the time you'll offer it high.
you may ever have to buy it in a low price so sell this not just in a high price but for the price wherein you can gain profit for it it can be a little bit only what important is you can save all you can gain for it then start for a new one.
