It's always difficult to tell the price actually, so i choose a particular price and make it a target price for both buy and sell, If the price gets there; fine if it doesn't i will wait until the price gets there, there is no need chasing for price rather set your own target price.
agreed with this strategy wholeheartedly since I too always considers this strategy and make use of it, i'd just gonna bag some coins if the price reached my target otherwise i don't sweat over the coin
at all, it just easier this way honestly.
