Sometimes I will sell and buy back in lower price, but look at current situation I will wait untill end of this month or more, still trading when loss just make my situation worst.
This is a good strategy and needs to be emulated, always buy it back and do not be afraid of the price down. Prices offer and we continue to pursue until the lowest price. Wait and wait some time, be patient for a few weeks.
Always buy back when the price is really low. But others wait for the price to really go low before making a move, however I'm not a firm believer of it. If you have money then buy it as soon as you got the chance because the price is really volatile and chances are the price can rise resulting in you missing a opportunity to stash more in your wallet. So I don't like to wait, if the price is low then for you its already a chance to get it and sell later when the price goes high.
On market the price not always falldown, sometime after a time downtrend, the price of crypto on market will create some trap "recovery" and you can take advantage of it to make extra profit in short time. Remember just for short time, if you mistake please stop loss soon for keep safe your funds
