Oh OK. Changing model to pay per use is something we thought of but most people told us they would feel anxiety to search and preferred a fixed monthly fee. We are continuing to have an open discussion about this in Discord, our site and here on HN so lets see if we figure it out.
Prepaid doens't have to mean pay-per-use. It can mean I load up 50€ to my account and you debit 10€ per month until the account balance is less than 10€.
Some other pay-with-cash methods in other countries are paysafecash (like viacash), paysafecard (only anonymous if you meet strict KYC requirements), some gambling related one (whatever) and cash-by-mail.
Do note that all of them have significant fees and probably not that many users.
