I noticed some altcoin in coinmarketcap, and I see the coin keeps going down, which I ask, will the coin be lost if the price keeps going down, or will it not go away and the price will go up?
Many altcoins are going down nowadays and it is normal. People sold their coins and they are waiting with tether or USD. So it will not get lost all you need to do is HODL. It is better to do nothing when price goes up or down.
