It actually depends on the situation. If a person bought Bitcoin with his/her whole savings during the lowest DIPs of the bear cycle, then it would be the correct decision. You may call it "luck", but the right decision.
I would consider it a risky decision rather than a right decision. One of our main problems is that when we take a risk and when it succeeds, we consider it a right decision. But what if it fails? If it fails, let's not forget to make all kinds of negative comments about his decision.
Suppose someone bought Bitcoin with all his savings at the lowest DIP of the bear cycle, but could not do it long term due to financial crisis. Because he bought Bitcoin with all his savings. Then would you call his decision a right decision? Or if he lost his access to it in an accident or somehow lost his Bitcoins, then what would you call his decision? Good or bad?
Actually, I don't see anything wrong with buying at this time, but buying with all his savings at any time of the market is a wrong decision. Because it is a very risky decision. If you succeed, you are profitable, but if you fail, your life may be ruined. Because you will have nothing left.
There's a risk, but that's the difference between people who actually have done their due diligence on what Bitcoin fundamentally is/learning the basics of the technical side of things, what makes everything stick together, and its value-proposition. It is something that the world has never seen before, and something that the internet WILL and SHOULD have. It is this generation's tour de force, a great achievement.
Is there a DIP? Buy it and HODL.
But those situation cannot be learned in short period of time and we can't assume that everyone had a deep knowledge about Bitcoin so technically we cannot advice those buy the dip thing and focus on other fundamental things since there's provably a problem would arise for that matter.
Even those old dudes which have long experience trading on the market didn't know on when those dips would came. So to avoid getting any further issue and you won't have anything disappointing moment which could lead for dumping their asset. They better focus on accumulating if their aim is to HODL since for sure that consistent buying whatever price it is won't give them any issue and provably that they get inspired more especially if they see that the numbers of Bitcoins in their wallets is growing.
Take a leap of faith ser. There will be risks, yes, but if you truly understood what Bitcoin is, its ethos, its fundamentals, then it's a risk best taken. It took me one year to truly understand too, but I took the leap of faith during the DIPs of the bear cycle during 2019. But that isn't the actual risk though. It was the pioneers during 2010 - 2012 that took the actual risk, and look where they are now.
