In fact, everyone has their personal reasons why selling altcoin so quickly before they make a profit and switch to buy bitcoin. In fact we can not know the exact reason whether they are selling because they really need money or just follow the issues that occur in the market. If we sell our altcoin after hearing an issue in the market that could be the price of altcoin getting down then it's a mistake. We are just a victim of a misleading issue. In playing crypto currency we should have a strong stance.
I agree with you. Because of many circumstances people were selling their altcoin so soon. They are afraid to loss their profit and can't recover it again. So it is better to sell it and buy bitcoin for long time investment.
