I don't think it will be a wrong idea if an investor start accumulating bitcoin and at the same while working on his source of income because I don't prioritise waiting.a newbie investors can also decide to cut down on some of his expenses and use the money to invest in bitcoin.There are people who has formed the habits of womanising, clubbing, drinking of alcohols and smoking etc.if an investor decides to quit some bof this habits which I believe he can deal without, and use the money to start accumulating bitcoin.so a newbie who is financially stable can be accumulating bitcoin an at the same while working on his finances.
What you said is also a very good idea for novice investors in Bitcoin who are still struggling to be able to invest regularly in Bitcoin, it is indeed very necessary to avoid spending money that is not important in their lives as long as the habit can be abandoned without having a mental burden. Because from some of the habits you mentioned, they are habits that often spend money uselessly, so it would be very good if the money used for this was used routinely into Bitcoin investments. Meanwhile, other income must be continuously worked on, especially if it is a daily job in collecting money so that some of it can be used to buy Bitcoin so that the number of Bitcoins in the portfolio can increase over time.
I can't argue with this reasoning pattern in any way, most people spend an unnecessary amount of their income on things they can do without, but they spend this money believing that sponsoring this lifestyle is the way to go, this makes investing in bitcoin as a newbie difficult because letting go of the funds for the necessary period of time needed to make good profit out of your investment (4-10 years) becomes unrealistic to them, also the use of discretionary funds for investment is advisable so as not to worry too much about the rise and fall of the market value of bitcoin.
A newbie should also have plans for a steady inflow of cash if they intend to invest in bitcoin, this way the amount of fund invested can be increased either weekly or even monthly depending on how much cash comes in at the end of the day for such person.
Bitcoin investment is too volatile for a person to monitor with an uncertain mindset, this could lead to the person selling their bitcoin at a time when the market value is low out of the fear of losing out and this can/will ultimately lead to them losing out when the price skyrockets.
