On a blockchain app, your users will always fight each other for blockspace. Because there is only a given amount of bytes available every 10 minutes, the more users you have, the more expensive it will become for each user. Which make users move on to cheaper apps as your app grows in usage.

It is shocking to me that some devs still don’t get how blockchains will always work against their success.

It's all looks great when you don't have any user.

Nostr fixes this.
