I disagree with you dude, because no matter how much someone wants to invest in Bitcoin, that funds must come from the person's discretionary. Remember that an Investor always allocate funds to different needs and wants and these funds should be used for a specific task and so using money outside your discretionary is not advisable and it is a wrong investment and JJG has explained this before now. Even when we want to be aggressive, it is our discretionary funds we will use to...
I believe that these two sides here are pointing at the same truth in two different directions. The thing is that good Bitcoin investment is reduced to risk management, and this is why discretionary income is frequently suggested to people, as it means that you will not be forced to sell all your assets to panic in case the costs of life will appear. Meanwhile, there are more highly-convinced investors or better-financially-shielded investors who make far more aggressive allocations, and history tells us this has been successful in the case of some of them. In my own case, I would consider DCA with discretionary funds as the most secure long-term course of action, whereas I would consider dips as an opportunity to be a little more aggressive provided that your financial capabilities permit it. In that manner you would develop progressively without putting aside money that you could require the next day.
What I find very practical is that investors prepare for dips and not treating dips as an emergency activity and ending up going against their financial discipline to entertain dips, using money meant for something important to pursue dips is a very bad cashflow management practice and would be better if the investor who wants to buy a dip saved up for the dip alongside his consistent bitcoin purchase and buys the dip when it presents itself from already saved funds in that regard.
