From http://cryptomarketplot.com/cmp-faq.html : What exactly does 1.23e-4 means? Why do you use the computer form of scientific notation? We use scientific notation to remove the leadings zeroes. What is simpler to read quickly, 0.000123 or 1.23e-4? If you trade crypto, you usually already know by heart how many zeroes are in front, and what is the approximate price range - you only care about the changes of the non…

And between 0.00000123, 0.000123, 0.0000123 you are sure which one is which without effort?

I can't

Percent change, you mean you want the equivalent from the original CMC JSON: "percent_change_1h": "XXX", "percent_change_24h": "XX", "percent_change_7d": "XX", We can add that, but we want to use fixed points in times, to avoid floating periods comparison. Here is an example for the change in 1h: it is 10:45 AM, so do the average for 10AM, do the average for 9AM, see the percentage change. A bad method is to average…

what CMC does is what everyone does, i think it's the standard method. From your frontpage it seems u already have those values somewhere

We have many values, but if we think they may mislead people, we don't show them. It is our ethics. We do not want to do what everyone does.

We will show more coins when we think we can show non misleading data. It's a question of trust. We want happy visitors and happy clients. We want to earn their trust.

Thanks for a lot for using our data on coinzaa! We would appreciate a link, but only if you feel like it.

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.

There is no universal way to write something “as an acronym”. Capitalization will always be on a case-by-case basis.

“Tor” isn’t really even intended to be an acronym anymore. It’s just the name of the project.

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!

The real work is to spot the anomalies, so your averages don't deviate from real values and I think that's what makes Coinmarketcap reliable. If you say you made it for hobby, how are you trying to replace Coinmarketcap?

1996 is rate limited on the replies, so I'll answer: Until it brings in more money than it costs to make, it is a hobby.

I hope we grow and replace coinmarketcap. But that will take hard work, and lots of luck.

We have algorithms to spot anomalies. We want to offer extremely reliable data.

Hi 1996 - I used to work at [Cryptopia]( https://www.cryptopia.co.nz/ ), a exchange fairly well known for listing low marketcap coins. If you ever decide you want to expand to more than top 50 coins, then I'd love to help in any way I can - particularly with their API - feel free to email me: "james" at $my_hackernews_username ".nz"

Hi Scaur!

We are on #1 page!! Big surprise !! Now I have to reply to all questions but HN tell me 'you are posting too much'

I must fix bugs first, but I will be happy to email you!! I love cryptopia and it's approach!! Our email is in the faq: cryptomarketplot@protonmail.com

There is more on the website than the eye can see now. We will unveil new features soon.

Expanding beyond top #50 is something we want. We want to support more coins, and there is work in progress on that.

But after noticing what coins it will expose, we almost changed our mind and decide to just be top20.

After hard thinking, we decided to spend much more effort on methods to flags suspicious coins. Because there are many small promising coins that can benefit from exposure.

It is almost there. More algorithms to make!

Have you evaluated cryptoquote.io? Take a look at their real-time level 1 and level 2 websocket APIs. They seem to understand market data and have navigated the non-standard connections to cryptocurrency exchanges well.

They want a login before even giving a key.

Can you summarize their features? What data do they show?

We offer real-time data to clients. Real time is hard to beat.
