Is there online investment that return 50$ daily
If you have a big enough capital to invest then the next thing you would need first before using that capital is to invest time and effort in learning about good investments and choosing which industry would suit your investing tastes/plans the best. If you do this right, you'd be able to earn so much more than just $50 daily.
If you lack funds, then learn new skills and earn that "big enough capital" so that you can proceed to the next steps and finally reach your goal and maybe more. Just do your best to be consistent with your efforts and try to not be too impatient so that you can make sure you do things in the best way possible for you. Even if the world betrays you, your efforts won't. Hope this helps.
Based on reality, and practical indicators of 10-20% per annum, then in order to achieve the goal of $ 50, the topic creator will need to find and invest somewhere:
from 50*365*10 = 182.500 dollars, with an annual income of 10%
up to 50*365*5 = 91.250 dollars, with an annual income of 20%
In a word - nothing is real
PS Yes, taxes are not taken into account in this scheme, so the author of the topic can adjust it to fit his legislation and get a ready-made business plan to receive $ 50 daily
