Why much emphasis on reserve funds @Cryptmuster, when you could just keep buying always using the DCA and continue boosting your portfolio. You sound as though the major thing to do with our discretionary income is to build more reserve funds rather than continually buying some chunk of BTC consistently and building your portfolio. You could also read the points of Sir JJG for more insight on this.

If we are able to figure out our discretionary, we must be consistent to buying Bitcoin and also building our back up funds, as well as trying also to place some amount for your discretionary consumption. Perhaps, every investor must be careful to ensure they doesn't mix there priorities wrongly in putting more attention to what doesn't matter much. Investors must ensure to strike a balance between there income allocation into different segments of there investment and there personal lives to ensure steadily and progressive investment journey.

 Much emphasis on reserve funds points more to relying and/or preparing and waiting for the Dip so to buy from it, when we don't even know when it may happy. DCAing consistently is more important and reliably good for building our portfolio in a long run.

There is no right time to invest, every time is a good time to buy Bitcoin. Because Bitcoin is still in its early stages. A person who waits for a good time right now will only be left behind and may never build a portfolio or buy with that amount of money. Every time is a good time to buy Bitcoin, instead of waiting for the right time, it is a better decision to continue buying continuously through the DCA method.

Instead of saving separately to buy aggressively during the decline, if he combines that amount of money with his continuous investment and continues to buy aggressively, then he may get a better result in the future instead of waiting.

These makes me to give a direct answer to the heading of this thread.
"Does the DCA strategy inspire newbies to invest?"
Yes it does!

Definitely, talking about reserve fund in the crypto space for flexible investing fortells the tendency of hoping or waiting to buy the dip which is not an ultimate idea. Having a reserve fund can likely happen as discretionary funds increases and in such situation, an investor can instead increase their buying percentage which implies being aggressive instead of keeping reserve fund out of increased discretionary funds.

Dude, you just quoted the wrong person, JJG was not the one throwing emphasis on reserve funds but you quoted him instead of the person you are talking about and I believe that is wrong because you can not quote another person and be replying a different person that is misquote, even though the person's quote is embedded in the post. However, I think it will be wrong for someone to be paying more attention to reserve funds instead of thinking on how to grow their portfolio because reserve funds doesn't grow portfolio  but discretionary income does.

While you may be fine with DCA, the leverage issue seems to be going in the opposite direction. We know that DCA allows us to buy Bitcoin regularly within our means, considering the risk. Leverage, on the other hand, is a term that means that you take on risk from someone else to expand a position, which increases the risk of liquidation or forced losses. Especially a newbie struggles to adapt to the volatility of Bitcoin. Adding leverage there means that it is no longer a matter of calm savings, but rather a matter of betting on price fluctuations.
