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
it is not that easy and "fast" you don't buy and then sell right after.
first you find a low price lets say $400 then you place buy order to buy at $400 or wait and buy when the price is near that. they you place a sell order at a higher price lets say $420 now you
wait until it gets filled.
the important part is choosing the low and high prices. and remember that the wait part can be 1 minute to forever.
