Bitcoin Forum

I'm looking for a website that gives me the Bitcoin price for any date, in such a way that it can't be debated.
Usage: I want to make a prediction contest, in which the price on November 1 at a certain time(zone) has to be predicted.

Coinbase (https://www.coindesk.com/price/) allows me to export data, but it can be debated. If I compare the CSV for 1w to 3m, it is inconsistent: at the same time and date, the price can vary slightly.

Bitcoinaverage (https://bitcoinaverage.com/en/bitcoin-price/btc-to-usd) has a graph that I can read the price from, but it uses my local time zone, and depending on how far I zoom in, it gives a slightly different price again.

What website can produce this? I know there is of course no "exact" Bitcoin price, but as long as the site gives a clear answer and nobody can influence it directly, it's fine by me.

What about Bitcoincharts?

https://bitcoincharts.com/charts/bitstampUSD#rg60ztgSzm1g10zm2g25zv

Tradingview https://www.tradingview.com/ is a good cryptocurrency charting site, so is CryptoWatch https://cryptowat.ch/  Both have historical data and list many different exchanges. You can even publish the charts you create on Tradingview so you can link to them from other sites.

"Load raw data" gives a table, but it has the same problem Coinbase has:
When I look at the 2 months Time Period:
Closing value on 2017-10-10 00:00:00: $4817.99.
When I look at the 1 day Time Period:
Closing value on 2017-10-10 00:00:00: $4793.72

I would expect the closing value to be the same on both views. Maybe my interpretation of what this means is wrong, am I missing something?

Bump: I still haven't found what I'm looking for.

You didn't read what I need, this is not at all what I'm looking for.
