You don't expect a newbie that does not understand how the system works not to be worried about the price of Bitcoin when he or she wants to acquire the asset, although price check sometimes discourages individuals that are ready to embark on the journey, a newbie at first sight doest not understand what Bitcoin price fluctuations is all about until he get involved, you understand what the uptrend and downtrend of bitcoin is because you are aware of bitcoin concept, although your advice is in the right direction but intending investors will panick or be afraid because they aren't conversant with the market, buying when the market is dip is the right approach for an intending and existing bitcoiner but if you can't wait till the market dips, buy the liitle you can to avoid  squandering the funds meant for the said investment.
