Right now the coin values are all in USD. The API supports many reference currencies, so adding at least some simple support for some world currencies would be a really nice enhancement.

AC:

• A control to change the reference currency should be added
• Changing the reference currency should initiate a new API request, and the interval request should continue onward with the new currency.
• A reference currency must be selected
• Defaulting to USD is fine, although being smart about it would be really cool too.

There are no tests. There should be adequate tests.

With a lot of coins on the screen, users might want to be able to sort by price, change, name, symbol etc. Additionally, some functionality to make it easy to track each row might be nice -- if you have 30 coins on the screen, it can be hard to see which values match which coins

The API comes with some pretty extensive history functionality. The initial, general /coins API call also returns some history, but it doesn't have timestamps like the linked endpoint. Example:

history | [ "53256.4571979186", "52957.7802322381", "51582.4966812654", "51741.1411412225", "51939.2866757594", "51439.0615168114", "51481.0918843304", "51949.550397478", "52211.0495918147", "52430.557307973", … ]

This could be used for a spark chart at the very least.

AC:

• Use the history data from either endpoint to generate charts, either simple spark charts or expandable tooltip-based charts (or both?).
  • Consider splitting if both are feasible and desirable.

Currently the page displays 10 hardcoded coins: Bitcoin, Ethereum, Tether, XRP, Bitcoin Cash, Binance Coin, Chainlink, Cardano, Litecoin, and Bitcoin SV. The API supports thousands of coins, and the idea was always to make this a nice, customizable view. Rather than hardcoding these coins, users should be able to add/remove coins from the list.

AC:

• A control to navigate all available coins and add one to the list should be available
  • Doing every single coin might cause memory concerns depending on the size of the API. There's no easy way to just fetch the symbols. Worst case scenario, just add a few hundred.
  • Once a new coin is added, the API request should be repeated, and the auto-update should continue with the updated list.
• Controls on each row to remove the coin should be added, and the API requests should be maintained similar to above.
