Considering that it almost touches the ATH few days back but from there on if we look slowly it started falling only and today went below 17k and now around the same price it is trading. So if we see this sort of thing happened in 2017 as well when it kept on falling and if it further falls then it may drag even below 15k which means going from bad to worse which we do not want to see that happen.
I was expecting a major correction before the new ATH, so at least for me this is not very surprising. The basics are still strong, and this means that even if there is a temporary dip, the prices are going to rebound in a short while. My only advice would be not to indulge in panic selling. The rally has just started, and if you sell your coins now, then you may regret about it later.
