In a slowdown market as currently, I was very panic and worry because the price continously dropped. I lost almost 80% of my investment at the time I sold it. Unfortunatly, after 2 days, this coin's value started increasing and it had a impresive recovery. I had a wrong decision at that time.
We are waiting for new and positive signals of the market when there is a increasing in price and value. At that time, we may reach optimal time of selling coins and get super profit level.
