You could be a millionaire not just by holding but also you need some stable bitcoin income to further increase your chances of being a bitcoin millionaire.
If you are just holding a small amount of bitcoin it wont help you at all, you need to grow your bitcoin so that becoming a millionaire is not a dream away.
