it is clear that you do not understand what pump and dump means.
pump and dump is a process where you increase the price of an asset which is worthless, to an unrealistic price with purely manipulation. the best example of this is if you look at the altcoins that go up in price. they have no usage and no real value, but they go up in price purely based on manipulation.
a pump never lasts long, because you are artificially increasing the price against the market. and market tends to correct itself at all times, keeping it up requires a lot of money and everyone wants to make money not to spend.
and as the name suggests it is called pump and dump not just pump. the dump is inevitable and soon after the pump not years after it!
with this explanation if you look at bitcoin price, you can see it is a solid rise with drops which are not as big as the rise aka corrections.
Well it has doubled in price in 2 months so I think that could definitely qualify as a pump. If more power players latch on during this pump (like amazon accepting bitcoin) it could turn the pump into a bubble but yes eventually the dump would happen. Who knows how long it could take. With small alt coins it could take weeks or months but since bitcoin is the biggest player it could take years. The players involved here are billionares so they have access to the best market research money can buy and will know just how high they can pump it before they dump.
Its not necessary to call that a pump! Two years ago many comments here were stating that someone is holding back the price of bitcoin. I said it before, its not impossible, someone with huge amount of bitcojns can control the supply and with that to hold back the price. Popularity of bitcoin raised a lot this year, and this can be a natural grow. People are more interested in bitcoins, and corporations, governments, some of them legalized bitcoin, and many other good things happened to bitcoin this year.
If you wish to see things objectively every market is pump and dump cycle, as demand and supply goes up or down price is doing the same. With every market can be manipulated and here bitcoin is not an excuse. Bitcoin will experience many more pumps and dumps before it settle, and that will happen in many years for now!
