It's good that you're starting to explore delegations — but there's no need to remove accounts just because you don't have 100 delegates🤣. That requirement refers to the number of delegations that account has received, not what you need to do.
You can also use Hive Engine, Beeswap, or Tribaldex to manage your tokens and see what projects are active.
The Hive ecosystem is rich and full of opportunities that will reveal themselves as you stay active and curious.
