One of my friend say, the panic of non believer is our way to make more profits. Thats mean our chance to buy more cause the price is dropping and wait a little but until gain profit from it. But dont be so naive though, if its time to cut some lose just do it.
yes indeed the right decision is needed to sell or hold a coin
Actually if we can think more clever then we can manage oir decision to make profit when the other panic sell.
But in the other side, we need spare money to buy more altcoin in the deep position. Without money then we can not buy again.
It cannot help you when you're panicking so i suggest to all of user of crypto dont panic when there huge dumping in the market. Also panicking make you do something that you can regret after what you do, so just be calm you can do buy and sell without panicking then when you're calm you can make wise decision.
