If you plan to be a long-term investor, there is no need for you to be waiting for no reason. You are already late to bitcoin and you don't see that as a problem which is why you think that the price is too expensive. How long do you want to keep waiting for two years or a year, because I don't see bitcoin price reaching the price that you are expecting this circle again because bull run is all about bitcoin price going up. Do you know when the next bear market will come, people are busy acquiring more bitcoin every week and month even with this price.

I will advice you that if you have the money to invest, you do that right away and don't wait in the ball park while others are busy piling up wealth for their future. Since you intend to buy and invest in a long term, it's good you start buying now with an amount from your discretionary income that will not be a problem to you so that you can continue using that amount to buy bitcoin every week through DCA method regularly for 4-10 years and above, so that you can keep your bitcoin accumulation ongoing and build your bitcoin stash bit by bit overtime.

I guess that you are missing something, at this current time people have understood the potentials that bitcoin have as an asset that is still in his transition stage and they are using this opportunity to be buying bitcoin for the future because they know that the value will increase overtime, and whoever is not in the accumulation train and has no bitcoin is missing out this unique opportunity bitcoin is giving you to secure your future by investing and hodli for long.
After listening to you I can convince myself to invest in Bitcoin again. Although I have little knowledge about Bitcoin and I think this knowledge is not enough yet. I have invested very little in Bitcoin, which has given me a good profit. But now that the price of Bitcoin has increased, I am getting more and more worried about investing or to be honest, I am a little afraid. Because I am a child of a middle-class family and I have to think very carefully about what I have to do.
However I think I want to use some of my money to invest in Bitcoin for at least another year. If I could get some more advice from you on how wise it would be, I would be very benefited from my heart. Because my Bitcoin journey is very difficult and ignores family opinions.

The dip is what people use to decieve themselves from getting started immediately and later get discouraged when they can't buy from the dip because it took them unaware. No one knows when the dip will come so start your bitcoin investment right away because the size of your bitcoin portfolio is what matters in future.
