Judging something not only from the name or brand of the coin, but look at the movement or potential value of the sale and purchase so that now you are surprised by the price that has reached 40$, so you don't want to hear the words of your irresponsible friend who misjudges a coin just from its name but look at it from the quality side, the potential of the gems will make you regret for the rest of your life, and this is a valuable lesson for you and all of us in choosing valuable coins, each of us needs analysis and belief.
