I usually like to sell my coins and then delete my watchlist and never look at it again. Just now, I accidentally saw a tweet from someone mentioning a coin I cleared out before a big surge. At the time, after buying it, it kept falling; the trend looked like one where it seemed there was no support and selling pressure was high. In the end, I just happened to sell at the lowest point, and it has surged five times in the last two days. I bought it for 600 USD and ended up losing 400 USD 😂
