That's the opinion of every person, but for me, this is the moment to sell, Bitcoin is a little bit instable, it's going up and down very frequently, I expect it to rise up to 3000$, but after a dump to 2000$.
For now, the right decision is to sell.
This will be your decision. Most of the users want to save their bitcoin because they all know that they will be seeing a pump after these network splitting. But before that there will be a dump, so I think if you sell now, that will be profitable, and then when it dumps, you buy some coins and save it for the pump.
