I don't think you should be concerned about others sentiment because even though the price has gotten a huge DIP so far, some people will still be waiting for more further DIP or will be dreaming of a massive dump before they can buy and they will keep on exaggerating before they know it the price will recover again and they end up not still buying at the DIP price they have been waiting for. Those who will buy Bitcoin despite the entry price will still buy whether there's a DIP or not so don't be too concerned about those procrastinators in the name of waiting for a DIP price to buy.
Even though we don't know how far the market will dip, I think anyone serious with buying the dips should have had majority of his orders filled by now that market moved from $70k few days ago to $50k today which is a price differential of about $20k representing 28.6% drop in price. If this is not dip to anyone, maybe the person is expecting a bear season before he consider that a dip. What the market is doing now is correction and for an asset like Bitcoin that is very volatile, over 20% drop in price is a huge retracement and a good opportunity to take buy positions. It is possible the price will go lower than this or and it is possible it will not but the main point is that anyone buying the dips out to have taken some good positions by now, keeping just a small fraction of his fiat should the market go lower.
Anyone who is panicking now that a DIP is happening does not even understand the reason why they have Bitcoin because it's either they lack courage or they are hoping for the price to skyrocket so that they can sell. Why monitoring or viewing your portfolio when you already know that corrections are meant to happen in the price of Bitcoin. The earlier we develop a strong confidence in the ability of Bitcoin to survive despite all criticisms and hateful words from the enemies of Bitcoin, the better for us all. I don't see the reason why anyone should panic about the decline in the price of Bitcoin. It is a normal phenomenon.
Most of the lessons from this thread is how not to panic especially in a time like this because it is nothing new. Consequently, when we see this market condition, instead of panic, it should be a time to make smart decision that produces more Bitcoin to the collection at very discounted prices. Besides, it is also at the core of our discussion here that provisions should be made for a time like this so that we will never have any reason to fret or feel any urge to sell when we do not plan to do that. The present market condition is rather a good opportunity for more investments and not a time to panic.
