Which model has been more beneficial to you, when you think of investing time and resources to earn a passive income?
Neither of the model is actually not a passive income, because you need to excel an effort to any of that model to get significant income.
Move to earn doesn't seem beneficial from the financial aspect in my opinion, because the coin you're earning on most of the platform are very little that it would literally take you a while to accumulate enough coins to qualify for the minimum withdrawal.
On the other hand, play to earn model will require you to at least spend a few hours everyday to keep the earning mechanism running. You will also need to spend money for you to maximize the earning potential and not to mention that you also need to compete with other players.
Therefore, both needs extra time and effort that would hinder your time with your business or 9 to 5 job.
