Are you looking for the perfect cryptocurrency? Try the Bitcoin Network.
I originally tried a really cheap VPS with spinning drives (and probably over subscribed) and that was a disaster.
My current VPS has 3GB of Ram and about 60GB of hard drive space similar to the 3GB model here:
I've found Racknerd to be an excellent provider with great pricing if you can snag one of these specials.
The only constraint is storage as Mastodon caches images and will fill the drive even with only me on the instance.
