This is the part that most persons has failed to understand that is why some people make mistake in there investment and the earlier people understand and know that Bitcoin is not a get rich quick or a Ponzi scheme the better for them. Anyone who is actually serious to invest in Bitcoin won't wait for Bitcoin to first Dip, anyone who is waiting for Dip when he or she have not invested before is showing a trading behavior because if they buy during the Dip they will want to sell when the price appreciate but an investor who is serious will invest regardless of the state of the market using the DCA method.
anyone who taking bitcoin to be a get rich quick or Ponzi scheme will never make good bitcoin investment, because that mindset that he or she is using to approach bitcoin is a wrong approach and it may not end well for the person, so best way to approach bitcoin is to understand how bitcoin works it use cases and the risks involved first before accumulating bitcoin to hold, and the holding should be for long term 4 to 10 or more depending on how long you'll be willing to hold your investment.
And secondly anyone who is waiting for the dip before he or she will start accumulating that person is not serious and he or she can never accumulate a good portion of bitcoin to hold for long term if he or she continue waiting for the dip, just JJG has keep saying that waiting for dip may delay your bitcoin investment journey, so for that reason one should start as soon as possible to accumulate bitcoin with the DCA consistently and hold without waiting for dips and that's the best strategy suitable for bitcoin due to it volatile nature.
