I want you to understand that everything is possible, you must have belief in yourself and begin somewhere. Many successful Bitcoin investors began somewhere, not everyone begins their investment path with a steady life. Even people who are having trouble managing what they spend every day can still invest, but they should remember that the money they are investing is for the future and that they may lose it if they decide to sell it.
It is not advisable to encourage to some one who is still struggling with his life and daily living to invest into Bitcoin for it won't work out which money will such person use in accumulating Bitcoin when he barely feed or what did you think will happen to his investment if an emergency or unforeseen circumstances occur don't you think he may decide to sell out his Bitcoin maybe even at lost for it could be that Bitcoin is at dip when he sell .
It is good to have a better cash flow before going into Bitcoin investment and it should also be the money you won't be need for long time 4-10 or more but it not be that you are still struggling with your day to day needs and wants to go into Bitcoin investment definitely it won't work.
