ppq.ai looks cool. Other than the ideological aspect (pay using Bitcoin for a few indiviudal queries), did you calculate from what point it's more interesting to pay the monthly ChatGPT 4.0 membership and until when it's interesting to pay by the query? I also notice it has a search function, which the standard ChatGPT doesn't. Does it work well to search through your old conversations? I find myself asking the same things over and over again as I can't be bothered looking through 100s of conversations.
