A friend and I have been working on a free embedable crypto calculator. It contains over 2,000 digital assets including LTC, ETH, bitcoin, ERC20s, Stellar assets etc. The exchange rate can be calculated into 5 different fiat currencies including USD, EUR, GBP, HKD, and JPY.
You can add it to your website within a few minutes and I created some educational videos showing you how for your CMS: https://www.youtube.com/channel/UCFUz39K6LLxxRYGcDSaO3CA
I think this could be a really helpful little tool for webmasters to improve user experience for free.
Would really appreciate your feedback.
Thanks, Chris - Coinponent
