Another thing is that guys sometimes get locked into shitty paying jobs, so sometimes they might need to spend some money (and/or time and energies) in order to put themselves in a place to be able to make better money. These are not easy choices, and the answers are not obvious since they likely take some efforts from the involved person and also sometimes based on a variety of preferences and the potential to build on already existing skills and characteristics.
Our energies are high while we are in our 20s or 30s and that's the time when we must not stick with our monthly salary (if it's not adequate). One must go for extra work to generate extra income that we can use for investing in Bitcoin. Also if it becomes our habit in early age to work hard then we carry that with us as we grow. Inflation and low salary should not be an excuse, we have other options to increase our earnings. These days inflation has gone up and people are finding it hard to live with monthly, it's essential for everyone of us to find some extra work to invest in Bitcoin.
Money is the means to own Bitcoin, unless it is gifted to you or you receive your payment with it, so aside from the gifting you have to work to own it. It is not enough that you have all the exceptional knowledge about Bitcoin and it's market, without money you cannot buy and hodl it, period!
I've always emphasized in some of my posts on this thread about the importance of moving out of our comfort zones and try to increase our incomes. It is essential because if you're still receiving the same income over time without any increase you will find out that it will no longer be sufficient for you. Fiat are prone to inflation so to be on top of your DCA method you have to think smart and find legitimate ways to increase your income. Get a better paying job, get a side hustle, learn profitable skills that are in demand so you can have a better life and conveniently funds your discretionary account.
If you're determined to constantly accumulate and hodl for a very long term you need to put in the work. When money stops to enter your discretionary funds it becomes a clog to your goal of long term hodl.
