I've tried delegating to projects before and I've once tried leovoter and steembasicincome but due to my small hp, I stopped, and tried to grow my hp first. I will delegate when I have more HP.
I think hsbi is more technical and it might be worth trying(again). It doesn't pay liquid hive but if you are posting few times a week or daily, you receive votes depending on your HSBI unit and balance... Idk if it's profitable or what the APR is but it's something worth looking into if you are looking for other projects to delegate to.
Thank you very much for your message! I've already tried that. However, with delegation alone the result is lower than being a curator with my HP (about 10% curating)
