How frequently is the exchange rate updated? The rate doesn't change when I refresh after a minute, unlike for instance CoinMarketCap, which changes all the time.
I've seen sites with similar services in the past, but it's always good to have more options.

That's a lot of decimals for dollars:

This looks very good, but I would have few suggestions for improvement.
If it's possible I would like to add custom colors for images, in case when people like me are using dark theme that makes value of bitcoin harder to read.
Maybe option of inverted image would be simple solution, or adding some custom colors is more complex alternative.

It's great to see that you have many fiat currencies offered but it would be better to reduce decimals or make them optional.
If you think decimals for dollars are bad, check out Venezuelan Bolívar Fuerte or some other currencies with high inflation.
Other thing I would correct and remove is using SAT for some shitcoins ^{(SoMee Advertising Token?!)} instead for one of most used Bitcoin units.

I just added ?decimals= so you can do:


which will result in:

This looks amazing!
Thank you for quickly responding here, and one more thing I was wondering if it's possible to change size of images, making them smaller or bigger?
Or I could just add red colored background so that will work for most color themes, both light and dark, and bonus is that this matches with current bloody market trend for Bitcoin



To make it look better I created alternative green version with Venezuelan Bolívar Fuerte:

You made a really good and useful service that can be used in the forum, the interface is simple and easy to load, but I have some notes:

• I cannot adjust the exchange rate or see prices on other platforms.
• The conversion cannot be reversed BTC<>USD OR USD <> BTC.
• Entering currency details needs to change (or change the interface)
• ADD snap/History price and current price
