Only two time I made money for the selling Bitcoin with USD and then buy at another exchange . That was really a cool moment for me to make a profit of 80$ in one minute of hardwork .
And second time I made the profit with the adz coin bought at the yobit and sold at c-cex exchange , and made the profit of 0.04btc , that was really cool moment for me .
But after that I didn't get any chance to make because after that time I am facing the problem of the confirmation for the transaction of the Bitcoin at the exchange , usually it make one week to confirm , so everything not happen at the timing .
