I have experienced that countless of times in the past. One example was during the time when I was just a newbie and was just starting to get the hang of everything in crypto. If my memory serves me right, I bought some SC, XRP, Waves, and STRAT during the peak moments in the first half of the year 2017. Several months after I bought them, I was not able to make even a little profit. I lost my patience and sold them with significant loss. And then they all flew high in the last quarter of 2017.
