A "pump" is not real rise, consequently it can not stay because it is unstable and the resulting price is always above the intrinsic value hence a "pump" is always without exception followed by a "dump" hence creating the term "pump and dump".
Bitcoin is not a pump and dump.
We can only attach the word pump and dump to altcoins, pump and dump coins have a short lifespan in the market, something that is not applicable to Bitcoin, and other top coins in the market, we can use the word adoption or strong buy support in place of pump, I never support pump and dump coins because it has no value in the long run.
