Work in progress!

The linked graph are in PDF, and should update every hour soon.

The website is made to be fast to read, and give essential information. It should load very fast. No ads. No metrics. No bullshit.

The JSON API is similar to the deprecated CMC API. But no need of API key and you get not just the last price, but bid and ask.

Feedback is much appreciated!

Co author here - I make the API and the backend.

The numbers come from a large sample of exchanges, with several million new datapoint added every day to cover every crypto we find important.

It is more of a hobby for me, but I hope you like it!

Cool site! but:

Get an SSL certificate so you serve over https https://letsencrypt.org/getting-started/

Disclose the method and source

"average price on last calendar"

Average is a bad function to minimize error between expected values and actual values. Use median or median of the 5%-95% percentiles.

Nitpick: Your FAQ spells Tor as TOR https://www.torproject.org/docs/faq.html.en#WhyCalledTor

So, it's called Tor because it's an acronym, The Onion Router, but you're not allowed to write it as an acronym?

That's just awkward, it's not like they have a logo of a hill, they have a logo of an onion.

Cool site!

I am liking the non-linear x-axis on the slow zoom graphs. I had never seen those before. I just wonder why the resolution in the month and week part of the graphs is not so good? You should have many more data points than what you are rendering, shouldn't you?

I guess that you are preserving min/max in a period despite the lower sample rate?

I think they dont use onion routing anymore either but the name is the name.

On a different note, if you want to see just the value of your portfolio, you can use this site:

http://www.cryptoport.net/

You're supposed to save your portfolio as a bookmark. Therefore it's simple, has(almost) no JS, no login, no cookies, 100kb per page load, after that some 5kb.

It uses coinmarketcap though.

Sorry for piggybacking here but it might be useful to some.
