On my own perspective, wether newbies investors or not, it all boils down to the person in question, how much confidence and trust do they have in Bitcoin, because I have seen it on several occasions where veterans investors sell at a loss in panic, due to some dip in the market that was really hard for them to comprehend, ok let's look at this present dip in the market, do you think it's all knowledgeable and veterans investors that still keeps to their holdings? No.

Most investors including newbies investors or veterans that has all the required knowledge still panic, anytime their is a very strong dip in the market, and sincerely speaking, in my own opinion, it's because of we most times focus too much on the speculations on Bitcoin and what people with negative mindset about Bitcoin have to say, so in essence of what am trying to say is that, if you truly believe in Bitcoin, and knows what you are doing and it potential in the future, you wouldn't even pay attention to anything negative people have to say about Bitcoin, and such negativity is what makes people to panic  and start selling in a loss.

So the best way to go about it is that, as long as you are a long term holder, is to continue your accumulation through the DCA accumulating strategy and ignore all what negative people have to say about Bitcoin, regardless of whether their is a dip or not.
