Considering that if prices go 10x to 2 dollars, that amount required is 300 instead, it isn't looking too bad for the future as your vote value increases and on top of post earnings, you will also have decent curation earning some liquids too. At 40x where it was in January, you need 75 SP a month for rent. All things remaining constant, that means you can live for 153 month (12.5 years) rent free :D
