Hey HN!

I just created my first Chrome Extension. You can add all available coins from CoinMarketCap to your watchlist and track teir current prices and 1h change.

I am looking for some feedback and ideas to improve and extend my project.

Best Regards!

Good work. I'm curious which API you use (or many different?), because in comparison to other plugins you even support newly listed airdrops.

Another question: Is there any good approach to monetize a chrome extension like this one?

Thanks!

Currently I'm using the API of CoinMarketCap, which supports over 1300 coins!

To your second question about monetizing. You can publish and sell your extensions aswell. In my opinions, this does not make sense as all, as there is a lot of competition and most of extensions are for free.

However, I'm not trying to make any profits with this Project. It was just for fun and wanted to contributed something to the community.

What if it can receive the cryptocurrency data from Coinbase ?

Coinbase does only offer three Coins. I think it would not make much sense to use multiple APIs.

Since CoinMarketCap is migrating its API to a professional one, I am looking forward to chsnge the used API to the one of Coingecko. I could offer more than 3000 coins instead of 1300.
