Getting that snowball rolling again is absolutely the best idea.
Been rolling mine for a while now and it's getting bigger and bigger. Having a witness as really helped a lot being the majority of my earnings recently up until a few months ago where my curation rewards to witness rewards are about 50/50 now.
I would think it wouldn't take you long at all to get back to 30k!
I have been wanting to start up a witness. If I do it, I would want to self-host it. What is the best guide to get started with? I saw one from Rishi, but it was like 4 years old. Guessing it would be the same?
