After carefully reviewing the suggestions provided, certain changes have been implemented on 100 Bitcoin. Some of those are as follows...

1. BTC price in USD is now shown at the browser tab as well. So, you may work on some other tab and can still monitor the price change.

2. Page gets auto-refreshed every 10 minutes and so is the price data. One gets option to manually refresh before that as well.

3. Live data is now fetched from Blockchain.com, instead of CoinGecko.

4. Historical price data of current date over last 9 years in USD is now shown in a chart. One may download the chart in JPG/PNG/PDF etc.


OP updated with new screenshots. Keep up suggesting more improvement features. I'll work on to implement as much as possible.
