Dips are unpredictable, so instead of waiting for this period to invest, one should set a fixed source of income and prepare to buy bitcoins immediately i.e. buy bitcoins continuously and prepare to prolong Holding. By buying Bitcoin regularly you can take advantage of any time in any market.
The sky is not always clear, there are times when the Bitcoin market suffers and falls, it's just that, Investors don't know when that will happen. Some investors think that when a downturn occurs, the best thing to do is to take a step back and wait. However, this is a wrong assumption, as Bearish conditions are the best time to increase your portfolio and get more Bitcoin for the next market cycle.Some folks can be accumulating bitcoin aggressively but at the end they would endup ruin their bitcoin investment, Because they didn't follow the right procedures, by being over aggressive without any proper plan like having a backup funds ( emergency funds ), which may lead one to point of not being able to keep up with his expenses and same time with his investment, having the only option of selling off his investment inorder to keep up with his way of living and stuff.
My point is that Bitcoin investment is something one need to approach with proper planning , but with those planning and with enough cashflow. One can easily secure a long-term investment in Bitcoin.
I don't really disagree with you, even though you do seem to imply that there might exist some higher level skills to invest in bitcoin, which there aren't - even though the more aggressive anyone is going to be in their investment (in regards to using a lot of their discretionary income) to buy bitcoin, then they are going to be more prone to negative consequences if they screw up their cashflow management and/or make mistakes in their figuring out and applying their level of aggressiveness.
Persons who choose to be less aggressive in their bitcoin investment (accumulation) approach will be less likely to make mistakes with their cashflow management, even though they would not necessarily be as advantaged as the more aggressive bitcoin investor in the event that bitcoin ends up continuing to perform well as it has historically done.
