-i wonder if it did not changed since the fee for a post got higher from 25 sats to 100 sats ?

-100 sats represents 0.0583 euros may be psychologically it is a lot...

-If you spend more than you earn, it s a bit normal that you do not want to zap (especially for newbies, you are not aware of all the guidelance). May be if someone subscribes, it can be helpfull if he receives an email with the main points

-You should add a reminder "by giving sats you earn more" may be in each topic (as a highlight at the begining a topic page)
