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.
