I have the same doubts, now I have investments in index funds... seeing bitcoin prices it is a bit scary to invest in this asset. Apparently people have a lot of confidence in bitcoin and many people think that it has not reached its peak. I will try to invest when I can, because at some point it will go down and you can buy a little cheaper ... for now what I try is to inform me as much as possible, it is a complex world and you have to be very well informed.

If you are confident that you can survive in the long run then making reservations for investing this period when the price is high up this level should not be scary, we are experiencing the bullish part of the market and yes it will come to a stop where the market turns down the opposite direction and the prices will become low and much lower that we call it the DIP, those who had options for the short term will keep complaining and those who already have their priorities straight and accordingly will be glad and expect further DIP to happen because they can get Bitcoin cheaper. With the confidence you said you have, then you should sense no fear, if you want the quick profits then you can talk about lump summing at this price then hold for a while until 2025 when we will have the biggest ATH of the market.
