The price of cryptocurrencies basically follows the rules of demand and supply. As the coin becomes scares it becomes more valuable and hence the price increases. One common mistake most investors do is that, once they see the price of a coin is going down, they hastily dump what they also holding which increases the supply more than the demand and further reduces the value of that particular coin. Later we try to put the blame on the team that they are not managing the project well. Let's help sustain our coins by avoiding panic selling. Its a collaborative effort.
We just need to hold while the market is not bullish to give us profits. Only those have patience will survive in this technology and we know that this will bounce back but I think this will take enough time to recovers. Be patient and don't panic as the bull run will come at the right time. It's difficult to do but we must control our emotions and think for the future.
