I have been waiting for Bitcoin to reach $3000 so that I can sell my Bitcoins, but seems as if it doesn't want to reach that value anytime soon. SHould I sell with the current amount? 
You do not have to wait too long. It will be very soon.
a few months ago I sold bitcoin with unstable, that time I really need the money so the bitcoin I save it I end up with my currency exchange rates, but still left a bit right now I'm still waiting for the price of bitcoin until it reaches $3000. I expect this is the beginning of the bitcoin with increased again until early August
I think we all need a little patience in getting the price to reach $3000. Its been a very slow phase last week but I'm seeing a positive gains. We are now at $2600 and its a good sign now that we are moving to a positive direction. But as we all know bitcoin price is unstable so I'm expecting that it can't be met this month. However, after Aug I'm seeing another growth that will push bitcoin price to $3000.
