The price of this coin, MERL, fluctuates wildly and is really not suitable for trading volume. Bought at 1602U, sold at 1589U, a loss of 13U on one transaction. The key is it can instantly lose over 40U. If you can't maintain your composure and watch it drop lower, you might panic. However, after you cut your losses, it not only rebounds but also exceeds the original buying price by a lot. But you are not the market maker, so you can't predict the next second's rise or fall. This coin's top 10 accounts for 90%, clearly a strong market maker coin. Friends who want to trade this coin should definitely pay more attention to the K-line and only act when it is relatively stable.
