Due to rising rental prices, I have a suggestion, Why not have 12 hour rentals that are half the rent value of 24 hour rent money and can be used according to timezones. For eg while the eastern time-zone sleeps, they can rent their card for 12 hours and earn while sleeping.
It will also increase the supply of cards as well as bring down the rental prices.
The prices have inflated a lot due to influx of new players.
With the last stats reporting 50,000 active users daily, newer players need to keep up with older players and also advance through leagues by meeting the minimum power requirements.
So, this is my simple solution 12 hour rent contracts. What do you think?
