In the long run whatever you do you will be satisfied.
I remember talking with friends about buying in 2018 and some bought and regretted it, some did not buy. In the end those who did not buy never could find the right time and price to do it. It was always too expensive for them. Those who had regrets but held, eventually got so much profit that they turned into permanent holders. When I asked them a few days ago if they're planning to sell what they bought in 2018 they said no
That's sort of me, and I am quite happy about it. I didn't buy during 2018 I have to be honest, but in 2020 during early April when it was very low, I bought some and I assumed it would go to 13-14k prices when the halving happens and some time passes.
To be frank my goal was to reach 13-14k prices these days, so hold it for nearly a year and get a 2x return, that was my "hope". Now we are so high that I can't get too scared about any fall. Sure I would love it if bitcoin price could go to 100k, but that doesn't mean that I would be sad about the current price neither.
So long story short, we are doing fine for me, it is all about buying at the right time. I have a friend who is already very rich, he has millions of dollars, all made from early bitcoin investing but he got out a bit ago, and he kept buying bitcoin whenever it dropped more than 5% any day, he did that for years, and basically got so rich that dude got out with a lot of money but he already had some anyway, that is the power of being able to wait.
