Yeah, there's a limit in how many times you can tip. It's not realistic to expect limitless tips, as it's not like the site owns BAT, DAI or HYDRO, it has to be bought with ETH or BTC or in whichever way.
For publishers though, they can earn continuously, the posts never expire.
Oh that is a lot different than the 7 day reward cycle of Steem. Here every post looses value after 7 days.
If I intend correctly then a real high quality post could still reward the author several years later.

Yeah, when the new audience finds a post published last year, they can tip it still.
