We only get calm if we know that we are invested in the right and high-potential coin/s. I believe there is a reason for the dump but don't get bothered too much, it recovers back just like before. I was confident enough that we were not yet in the bear season but still on a bullish market and what we have experienced was a normal dumping situation.

They lose their money if they sell but if they just hold and wait for the recovery, they'll be earning more. So, therefore, choose those coins that you think will recover, not those coins that will die, or just choose only bitcoin for assurance, not altcoins. Most especially if they are buying meme coins, this will give them losses if the market continues to dump as I am afraid it will never rise again. If we trust bitcoin then I believe we have a reason also to stay calm and optimistic.
