My suggestions/feedback:
- A dark theme.
- Read the IP address, get the country and give the currency of that country. (If I'm from Australia, it should be AUD when I visit the site)
- The trading volumes... well, the numbers make
no sense at all.
- The share button is not doing anything, at least not in the exchanges pages.
I like how simplistic and easy to browse the website is. Good job on that part.
If you want to compete with Coinmarketcap, CoinGecko, etc. you'll have a lot of work to do...
Try to be creative and implement features that other sites don't have. If you don't have anything in mind, do what they have, but just better. If CoinMarketCap API has a certain limit, offer your API with better limits and attract developers as a start for example.
