- As a user, I want a Single-Activity App with BottomNavigationView that has 4 tabs A, B, C and D
- I can click tab A to view a market list with name and price on each item and sorted by name
- I can view spot/futures tabs at top of market list that I can toggle them to see list separately
- I can view a settings entrance button at top left of D page and I can click it to go to Settings page
- I can view the page name at the center of the page except A page. So I can know which page I'm viewing.
