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.

Don't allow anyone to influence you to start something you might not be able to control. Your investment is your responsibility and no one should makes you think that Bitcoin will continue to go up forever. It is possible that we might see $150k or even more but the truth is nothing is really certain for now until we see it and if your mind doesn't bear the risk, wait on the side. Nobody says Bitcoin wouldn't come down, it can't go up forever, that's how it has been I believe.
I want to see what will happen if there is policy changes that will favour Bitcoin but the more I look at it, I feel it's not coming as people want but I wouldn't be the first that will start the discussion so people wouldn't think I don't have Bitcoin to my wallet is the reason why I'm fudding and not been bullish. As I'm optimistic about the market, I'm also weighing other options.
