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.
People will panic because they lack knowledge. I dont think anyone following this thread for months would ever panic to sell their Bitcoin. Remember when investing in Bitcoin we understand that the price does not stay in a fixed position in real time it could be higher or lower than the current price. People who DCA would sit at their house without any emotional instability because they will not panic as long as they are holding it for years. The essence of having Bitcoin knowledge is important in times like this when the price starts going down. So that we won't make such a mistake or tamper with our investment, one time tampering with our investment could destroy everything we have built so far. This is the time to sit tight and take your mind off what is happening now and place it on what will happen soon or in the future.
You are absolutely right dude this is a nice period to build a great portfolio but we shouldn't get ourselves worked up or dry because of trying to take advantage of the current price of Bitcoin. Downtrend of Bitcoin doesn't mean we should go and invest what we can't afford to..., Because of you do and things went off balance ( if you have problem with your source of income) you may be tempted to go touch your investment when you are not suppose to... and at that point in time you will be seen as someone who doesn't know what investment is all about, so we should be wise while taking advantage of the market so that we don't speak trash about Bitcoin.
However, people who panics can not be generally seen as people who lack knowledge because we have traders and investors, so we can't say a trader lack's knowledge if he/he's is panicking because trading is very complex and you can't get your analysis right all the time but if an investor is panicking I can agree with you that he/she lack's knowledge because an investor is not meant to panic because of Bitcoin movement.
