Which model has been more beneficial to you, when you think of investing time and resources to earn a passive income?
None are beneficial to me, since earning in this kind of model is very hard. Like for example, earning in play to earn needs a player to spend some amount in order to gain advantage against other player, they need to spend money in order to get part of the money they spent, this is beneficial to those who have deep pocket but not on normal users like me.
While move to earn scheme also needs to purchase in-game items in order to boost the earnings thus, the models are almost identical to play to earn scheme. It can also be said that it is borderline a Ponzi Scheme where earnings and rewards came from new people that is introduced to the system and invest money in order to get advantage against other users.
Can the 'move to earn model' offered by a company like Sweatcoin, of whom are willing to pay tokens to users who have either sweated using the app while running or swimming, be a micro or macro solution to economic problems, if adopted on a large scale?
It is never a solution to both micro and macro economics problems even if adopted on a large scale. First, the token needs to have a value to use in real life world. To have stable value or have high liquidity it needs to be backed up by fund that can sustain the market value of the token. So the main concern is the source of fund to back up the financial activity. And where does this fund come from? Obviously, it will come from users and investors who need to purchase certain items to be a premium member. In the end, the users are first milked with funds before they can milk the system.
According to the business model of sweatcoin, they intend to gain revenue through merchant partnerships but this model is yet to be established.
Or would this 'move to earn model' just follow its hype and fade into existence leaving cryptocurrencies to be the only better innovation that is much more helpful to the economy?
They will eventually fade when new system of earning is introduced, or when their financial model collapses. We have seen several projects like these to fade into existence after some months of operation because they can't maintain the reward system or the value of their cryptocurrency in the market.
