If you see that the price is drop then should you buy it right away. It is normal happen that sometimes the price of bitcoin is change. Because when the btc rise again we can sure that we earn profit. If we have already bitcoin we hold it patiently and wait for the time that the price will high.
Yes this could be the right time to buy bitcoin right after the price drop because once the price starts increasing then we will hardly get any opportunity to buy bitcoin before it reaches moon. I think we all should assume this as a investment phase and invest but at your own risk.
