This statement  of yours shows that you may not have understood the concept of Bitcoin and what Bitcoin investment stands for in a long-term, so up till now there are still people doubting Bitcoin investment, that's so absurd to hear this,  when you say stronghearted i wanted you to explain further but you ended up messing the whole thing up, I think your doubt is too much about Bitcoin even after Bitcoin has made this level of progress this is funny, buddy there is nothing anyone should be afraid of in Bitcoin investment, as a matter of fact people like you needs DCA method because it willl help you not to be idle atleast yiu can keep investing the amount you can afford weekly or mothly steadily, consistently and may be increase your DCA level as time goes by when you're finally  convinced about the said investment.

You sounded as if Bitcoin is not trusted investment, this is an investment that has proven its authenticity and relevance for a good number of years now, mate your statemants looks like someone who's still on a long thing, I advise you to make the bold step if you haven't done that already to avoid regret later,  how would martket fluntuation be a problem to anyone when it's what keep the system intact, even though you worry about the market price why not concentrate on using DCA method to accumulate your Bitcoin and avoid looking at the price at all time.
Mate since get to know about Bitcoin, has the price price drop without rising to a point that bitcoiners will say it has done noble? Talking about risk, what risk have you noticed in Bitcoin investment that's not part of the process?
I think you really need to stop some of this discoragemnt talks because you don't know who's is reading through the lines here, this could reset newbies mindset and you know what that means.
