Exactly, people misunderstand that people of any social class can invest in bitcoin as long as the have their discretionary income available to them, if a person can not afford to have some money left behind after paying their bill then this people can not afford to invest, if they decide to then they are gambling with their financial security and their entire investment will be put in jeopardy, so to invest, a person needs to secure their discretionary income and keep up their consistency.
Discretionary income is the key to investing in Bitcoin. Therefore, most people who intend to invest will strive to increase their income so they can allocate a portion of it to Bitcoin investments without disrupting their daily living expenses. I also quite agree with your suggestion, as the difficulty of investing consistently always lies in income, as it is the primary driver after establishing a long-term plan for investing in Bitcoin. And because many people are starting to realize this, many are taking advantage of various job opportunities to increase their income and be able to purchase Bitcoin more regularly every week.
