I will like you to see it in 3 ways.
1. See it as a correction that was bound to happen anyway, after the huge non stop buying for months now.
2. See it as whales cashing out and some noobs getting scared and selling at losses. (they will get to learn from experience later on)
3. See it as a Christmas gift, if you want to get in at a lesser price because later on, this year or next year, we are coming back at some point to test back the previous top. Some call it black Friday for crypto shopping.
Jokes apart though, there is really nothing to worry about. You are welcome to the volatile world of crypto. It is a bloodbath out there right now and they happen once in a while. It will pass and forget anything else you are hearing.
You have a good point. I notice a lot of people are holding their bitcoin for 2018 but I think it is the wrong decision to make (for now, we don't know if bitcoin will beat its record for highest price). If they sell their bitcoin a few days before 2018 starts, they might earn a lot of money. The decision to hold bitcoin cost them more and they will be forced to sell their coins if they needed the money. They should atleast sell their coins to cover for the things that they are required to pay. Anyway, its their money and bitcoin is all about taking risk. LOL
