rinse and repeat... it moves in cycles. set your alerts... when your alerts pop...buy...I like to set another round of alerts for the uptick (on the coins I just bought, and where I plan to sell based off of other average sized bounces)... Then once the bounce happens, and you've sold... you have another base to go off of, and you can set another round of alerts for the drop. As for the alerts that didn't go off... I just leave them in case they do go off. If enough time goes by and the alerts become irrelevant you can delete them as you've probably already set new alerts for that coin.
