if we someday get a "pump" then price will go from $6k to $600k not to $20k-$25k that kind of small rise is what naturally happens not because of a "pump"! a "pump" is a manipulative increase of price which is unnatural and because of it, the rise will be big. for example you can see altcoins and how they get pumped every single day. their pumps are 100%-1000% within one day.
also another characteristic of a pump is the upcoming dump of it which means when it is pumped then it loses ALL that gained price because it was fake. in other words if bitcoin was a pump then it should have gone down to $1000 not stay above $6k!
