I don't know how accurate James Howells' example is. But if you invest in Bitcoin in some way, it will eventually become a very big investment. Those who sit around thinking about it and don't invest in Bitcoin will fall further behind. If you bought Bitcoin in 2015 when the price was much lower, you could have sold it at a much higher price now. If you bought Bitcoin around 2015 and started investing, you could have made a lot of progress by now.
I doubt if there is any way they can meet up except guys are financial boyant enough to load up there bitcoin portfolio yet not every one will be able to so, even though lump sum is a form of encouragement or buying huge during the dips is what they use to comfort themselves yet I doubt they will be able to pull such buy in the nearest future they usually anticipate.
Which is a good reason for one to buy when you have the finance regardless of the price (DCA), dollar cost averaging would eliminate the regression that might take place when one is unable to satisfy their long waited lump sum or buying hugely during the dips.
