If you invested only to bitcoin and still holding, just keep holding, because as you can see, the price everyday is not always the same,
It could go up and could go down as well. Bitcoin will going to comeback not only on $13K but more than that for sure.
You are only almost 1 year in the industry, that's still early, you need more experience, and more learnings. But if you invested to many cryptos and making trades
everyday, that's a different story.
