I think that one of the big problems that #nostr can solve is giving the ability to freely publish advertisements for the purchase and sale of products and services

Since more and more barriers to entry are being placed on traditional platforms and more data is requested to be able to participate in them. With the aim of raising more and controlling

So nostr and other bitcoiner platforms eliminate the need to use platforms like fiverr, upwork, wallapop etc. That's very bullish
