Pump and dump scheme does not exist in Bitcoin market. If it has ever existed, it was long time ago, years ago when Bitcoin had smaller price and very smaller trading volume. Nowadays, you can see rises and falls for Bitcoin but not pumps and dumps.

It is true to use pump and dump scheme for altcoins, not Bitcoin.

DCA and hodl your bitcoins with very long term vision will help you get rid of fear of missing out, panic.
