I believe the reason why Gavin was giving out 5 Bitcoin free was because back then the value of Bitcoin was almost nothing compare to now that the value of Bitcoin is crazy. And some of the people that was dashing out Bitcoin and were using it anyhow are somehow regretting now because they didn't know Bitcoin will be this great and Bitcoin will continue to be great as long as it continue to exist.

As long as the DCA method is concerned I don't really think getting Bitcoin in years coming will be difficult because we don't need to buy a whole of it at a time but rather we need to get it little by little even as we are doing now because it is not even easy to get a whole of it now ( 1 Bitcoin) at a time. The thing is that, those who didn't invest will miss some good chances, currently people are still seeing Bitcoin as something that is hard to get reason because they lack the knowledge. However, it is not just about getting Bitcoin now but it is also about getting it and holding it for a long term.
