Yep. Markets seem to always go higher than you ever expect, and always drop further than you can imagine. Just be happy you aren't someone living in an alternate reality nightmare where they bought at 10K and it dropped to 3K (I'm not making a prediction, just an example).

At the end of the day you gained, not everyone can say that. I know someone who sold all of his 10 bitcoins for 800 dollars each last year. His Facebook post made me cry.
