Nostr can be hit and miss if your post gets seen because there is no algorithm pushing popular stuff to the top other than other people sharing stuff organically. If your model is to broadcast stuff, it is not going to work the same as other platforms. A few influencers have found the same 'issue', so don't take it personally. I think the organic nature of nostr is a strength because it developed a flatter network with less hierarchy. Nostr is also pretty saturated with Bitcoin stuff, so unless you are offering an exclusive take or something unique you will probably struggle to get the boosts. I usually appreciate your content and am glad you are posting here. Don't be discouraged because you are not getting the same response as on other platforms.
