to make money online I think you have to be able to manage your time well because in the online world there is no time limit, the most important thing is to always be active.
I suggest you stick to your main job and the online world is just one of your side jobs.
in this case you can get into crypto by being an investor or a part-time trader. good luck
Proper time management isn't new to our ears to hear these days because aside from our main job which is our priority, we need to find another two or three source of income especially passive ones which is the best and ideal. Being here in the forum doesn't require much time except trading because we can post in our slack/free time or after working in office. As long as we have a time to spare, that doesn't keep us from making money from other jobs.
The best option is to invest in long-term commitment like bitcoin or other crypto currencies because such option doesn't require much time.
Our main job mostly can't support our expenses, especially if you already have a family.
Not saying that as general but most of those minimum wagers are in need of side job where they can earn extra money, if lean alone with their regular salaries budgeting is really hard.
Thinking of a growing family, side job is very important and dealing it online can sustain the needs. If you have skills which you can offer online, the possibilities are big to more from what you are receiving from your day job.
