It is not advisable to sell when the market is going down, because there are many people here who bought the coins at the high value, so instead of selling those for the loss, it is good to hold until the market starts recovering.
Indeed! Market keeps on fluctuating so it's very important to learn where to position our strategies in a way that it works for us or if does not at least we learn from it. It's only us who can define the strategy that is effective and that we have to stick to it. Never depend on others as there strategy may or may not work for you. Market may be down for now but let's stay positive that it can potentially recover.
