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.
And i would add here that when people invest they better make sure to leave money in the bank, around $1000-$2000 could work in case something happens or if you need money for anything - Since you just can't use your Bitcoin if the price fell a lot under the price you bought it. And this is something that is constantly happening in this world.
If you have a family then you better don't risk losing your house and/or their well-being for anything in this world. A lot more money can be nice, but you can't play with something so important.
