Whoever there is a pump in the market, you think you should invest in Bitcoin and Altcoins and you may benefit from it. But after your investment, the market goes down, and you think you are losing money, so you sell everything, again when you see the market go up you invest.
This is not about emotion, this is plain stupidity and naiveness. If you knew that you're a newbie, I wouldn't even buy Bitcoin or Altcoin if I didn't know what's going on with the market. If you're gonna say that we can't blame them since they are just newbies, no, it is their responsibility to study cryptocurrency first before buying anything. Instead of earning money, they are just wasting their money on their own mistakes.
Most of us have committed this kind of decision before. We've all become newbies and gone through trials and errors since we can't invest and trade perfectly. It's just that we have learned through our experience. In case we made that move, there's still nothing to fear as long as we are holding a potential coin. Just focus on the long-term hold and wait for the perfect time to sell again. As we wait for the profitable time to sell we should also learn how to market moves so we can deal with it.
