I never agreed with the term bubble because people will not buy bitcoins without believing in to its future you cannot convince thousands of traders with a fake reasons. Bitcoin getting into this much higher levels only because of some reasons and of course it would be its potentials.

I do see bitcoin will be reaching price levels like $10k in coming years and there will be no chances for any downfall at this stages. Even if it will happen, we can see price will be bouncing back very soon. Holding will be the right option imho.
