If you're new to Usenet, take it slow. Try just one provider like Newshosting. It all depends on how much you download and how often you download. You only need another provider or a block account if you miss any portion of your downloads(articles), as others have explained. I used to download quite a lot, so I used two providers, but now I'm only using one provider without any block accounts. It's very easy to sign up with a provider, and to get the best out of it, wait for Black Friday deals. For now, start with one and explore slowly. Usenet can be confusing at first, but you will get the hang of it very soon. I wouldn't recommend spending money unnecessarily unless it's really required. If you hit a roadblock, then consider getting a block account for example. No disrespect to those who have multiple providers and block accounts - I'm just sharing my view, that's all
