Hopefully, it has started to happen now so that bitcoin and altcoins can continue to rise. Even if it is a temporary increase, it is okay because we can profit from the difference between the current and previous prices. This time, some people who already bought at lower prices have already felt the benefits, although not much and they can repeat it at another time. Even if they still want to wait until the price is back above $40k, that's also okay because we have different plans based on the market situation. And we do have to be optimistic about bitcoin's great potential in the future.
When someone has made a good plan for their future investment, then buying bitcoin in the dip might be a good option for them. As far as I know bitcoin has always allowed investors who are willing to buy bitcoin when it price down to make a profit both in the short and long term. This is simply an experience based on what we have seen so far in the market, but should not be construed as financial advice to influence people to invest.
I don't know when the bulls will return for bitcoin while in the last three months we have had a big drop (nearly 50%). We can expect a recovery and the price can return above $40K or higher, but there is always a worst case scenario that we have to be prepared for and we never know when it will happen.
