I need some opinion if panic selling can contribute of rapidly drop of the bitcoin price. If it is right how can we convince to the bitcoiners to not doing panic selling.
Yes, it is. You cannot convince people not to do panic selling because it is their own choice and panic selling is just a normal thing when there is a bad news going on in the crypto industry.
actually this is common, because the price is so relatively down then, many are panicked by this, and they immediately sell coins that they have without thinking long. in fact it is also detrimental to ourselves if we face situations like this with a sense of panic.
