If you are new to cryptocurrency trading, seeing your portfolio drowning in blood might be very depressing and you might be tempted to sell all of them to prevent more loses. But always remember the golden rule of any trading; sell high and buy low. The rule is very simple but most people tend to forget it as they panic and get overpowered by emotions, and that's the worst thing that could happen to any trader. Don't panic! Bear market doesn't last forever. Instead of overthinking about your losses, consider this as the best opportunity to go shopping. It's sale day!
