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 $380
there is a risk when you trade bitcoins, like you buy for 400$ and next day it falls down, but you shouldn't be afraid because that is not horrible thing just you have to stay calm and don't panic and don't sell your bitcoins, because price will go up pretty soon
