I think there is no need to wait for investing in Bitcoin. Because I myself bought Bitcoin when it was 25,000 and sold it at 40, thinking that this might be the highest price. If I lower it a little, I will buy it again. I kept waiting, but even after lowering it a little, the price kept increasing. I thought and waited a little longer, and after thinking, it reached 100, then I decided that there was no point in thinking anymore, I will buy Bitcoin with a part of my salary every month, so I started buying. Now I realize that I was wrong to wait. I think Bitcoin is an asset that may go beyond our reach in the future. So now is the right time to invest.
In Bitcoin investment you don't have to wait for a particular time before you start investing because every time is the wright time to invest, waiting for the price to dip before buying would even cost you more just like your experience because most times, the price does not fall but keeps increasing, and sometimes it even goes beyond the amount which you use in buying
Bitcoin remains the only trusted coin, and having it has to be risky,therefore you have to forget about your fears and invest for a long-term .
The DCA strategy is always available for you to adopt to consistently purchase Bitcoin without waiting for the dip , in as much as you apply it in the bit to accumulate you Bitcoin you will find it very easy to invest. DCA allows you to accumulate little by little without any stress on your fund as long as your discretionary income is available, you keep buying and when it gets to the dip, you buy more to add up to your existing investment, so that you will not end up losing the entire process of investing.
Therefore don't wait but buy whatever you can afford at that moment .
