You're welcome! You'll be surprised at what you can find for posting.
There are Leos who post about coin collecting and stamp collecting, so there is room for other types of finance posts.
Even if you still have trouble finding your niche or a way to intersect crypto or finance with your interest, keep in mind that "finance" is a broad umbrella term. It also includes topics such as personal finance, home budgeting, home economics, greater productivity from limited resources (such as urban gardening), person-to-person loans, negotiations at pawn shops, finding greater success at eBay or Etsy, making money with stock photography-- anything which helps you or others to make your money do more.
