Waiting for the price to drop before buying is another strategy which is buying the dip and not lump sum, an investor should use the dca strategy to buy BTC since it's something that is done regularly with out waiting for the dip to buy as such an investor is regularly dcaing he could also lump sum when an unexpected funds comes his way or also buy more bitcoin during the dip as waiting to buy is a wrong strategy most expecially to new investors.
You made a great point and I'm sure many newbies that are ready to learn will benefit from what you said here, buying the dip is not bad as long as you aren't waiting to buy when the price dips maybe some people will get this wrong but I will put it in a way that everyone will get the information right, buy the dip, lump sum and DCA are all Bitcoin investment strategy but what differentiates all is how they are been used, for many of us that understands how efficient DCA strategy is, we choose to buy gradually and consistently because we can actually use our discreationary income to invest, as a matter of fact we can use any amount within our power to invest using the DCA method that allows us to buy any period or time, this strategy called DCA knows no boundary, we can buy with it every season without waiting for nothing, when buying with this method we can also decide to set some funds aside to use in buying when the dip occurs but that's if it is what we want, but all I know is that waiting for the dip is not the right thing to do because it might bring to end of an intending investor plans of investing in Bitcoin.
You are right, there's nothing bad about buying the dip. But I feel newbies who wants to use that strategy must be focused and knows what they are doing. My advice to newbies is that if they don't know anything about Bitcoin, they should first implement DCA as their first strategy, so when they are already accumulating and also learning along the way, then they can use buying the dip or lump as additional strategy. Especially when Bitcoin prices is in a bearish momentum, that could be a great opportunity to accumulate more Bitcoin whilst also doing your DCA. Because of you decide to go with buying the dip as your only strategy, price might not be to your level of interest in a long time, which means someone will have to keep waiting until price falls. Where as they could have been accumulating small and steady with the amount they can afford until price luckily get to that place of interest. That's the best thing to do .
