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 book about this. It focuses on Forex - Forex being a lot like
Kraken though Kraken might not have a lot of liquidity - the exchange rates not moving quite as quickly overall - as when there is not a lot of capital volume being exchanged in the respective exchange markets
It is possible to turn a profit at Kraken, but when the markets are stagnating, it takes a little bit of time.
