That's why you should only buy aggressively during the dip if you have the financial leverage to do so, but if you don't have just move on with what you are doing weekly or monthly, their is no cause for alarm.
An investor can buy aggressively at any market conditions, I don't think it's ideal to only be aggressive when there is dip. It all depends on what the investor wants to achieve with his portfolio. Since long term investors buy at all market conditions, an investor can decide to buy aggressively when he has resources readily available irrespective of market sentiment.
I think it's better to analyze and study these dips whenever they happen. Rather than framing it as “Bitcoin proved everyone wrong,”
What benefits will studying and analysing the dip do for you as an investor? For me it's a total waste of time and energy. We all knew that there will always be dips as an investor so there is no point trying to analyse or study whatever might be the cause of the dip. Such studies and analysis is not really necessary the way I see it.
