I used CoinCap API. CryptingUp doesn't work, CoinGecko doesn't have candles. But CoinCap also has problems with candles. It returns nothing. I used WPF .NET 6.0.
My application supports the following functionality:
• It's a multi-page application with navigation.
• The main page displays the top N currencies by popularity on some market.
• Page with the ability to view detailed information about the currency.
• Page with the ability to view detailed information about the market.
• Possibility of searching for currency by name.
• Usage of MVVM.
• Light/dark theme support.
