Im in it for the long term, so I didnt cash out when it was high.
I dont have the time to do short term trading, but I do wish I would have sold at $19k and then rebought at $11/12/13k. A lot of good profits for some people!
I just want to see what happens in 2018!!! I predict it is going to be a crazy year, and actually make or break for bitcoin. It will be a huge success, or people will start to move away from it
