I have read and heard that one can earn and make good money with trading bitcoins.I also want to give it a shot.Everyone says the basic rule of trading is buy low and sell high but I am confused because which ever exchange I try,the buy rate is always higher than sell rate.How can one profit if sell rate is less than buy rate.If I buy at $390, the sell rate is $380
This is the strategy that most of the traders do, but the difference is to catch the best moment to buy low (at the lowest price possible) and after a few minutes or days/weeks selling at a higher price, it's nearly impossible to get instant profit because the price does not change too often.
