From the beginning of 2018 to the present, price movements have always declined. I will say more - a sharp decline in prices was very clearly observed. 2018 is the year when we have to buy as much as possible, hoping that next year we will get a profit from rising prices, because when prices are always falling, there will surely be times when prices will jump. The end of 2018 is the time when we all have to invest and wait for the time to make a profit in 2019.
