I've had this little side project in mind for a couple of years and couldn't pull it off until recently when i learnt about AI coding tools. I'm actually super happy with it - it's certainly better than my other BTC related sites i've created in the past.

  • GBP/EUR/USD values
  • Price data back to mid 2010
  • Price updates daily
  • Compare DCA vs lump sum over any time period
  • Dynamic / responsive design
  • Threw in a little price forecast tool too for fun

www.DCAinBitcoin.com

Please 1. share the site if you think it's useful and 2. share feedback on improvements i could make.

Where did you get the price data from mid-2010? data dump dates back to 2013.
DCA data ignores bitcoin withdrawal fees or the possibility that purchases may stop once or twice during DCA years.
I loved the design; it's among the best that offer this service.

Thanks!
In the FAQ below i do mention that this doesnt include fees, taxes, spreads.
I also let viewers know the data is from CoinGecko or CoinMarketCap. I think the historical data was CMC and the daily price updates going forwards are CG. The price is the 'daily close' which is somewhat subjective i know - but for DCA analysis i had to pick a point in time.

That's why I asked. The data from https://coinmarketcap.com/historical/ back to 2013; there is no historical data older than that.
It would be helpful to compare this data with gold, major currencies, and S&P 500.
