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

We could fix that, but I kinda like TOR.

Keeping it in all caps (like when it was just an acronym) puts it forward.

We want to emphasize our support of privacy.

Fair enough if that’s what you want but if you just make up how you name things it’ll confuse people. You wouldn’t spell PGP like PgP either.

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.

There's also https://coincall.io which lets you create a portfolio without registering as a user.

Thanks, I will see how they do it.

I don't want registration or even cookies.

This is really cool, great work! I am one of the developers of Blockmodo. It offer realtime data streamed directly from the exchanges via a WebSocket API. Alternatively, you can also go through our REST API as well to get this data. Data can be streamed aggregated or if you choose, you can also stream and poll the data on a per-coin basis. For example, if you want the aggregate price of Bitcoin you can do that but if…

Huh, thanks?

But that's a bit different from what we are doing.

We concentrate on hard numbers and privacy. You seem to focus on news and community. And it seems to me your API requires a login. Also, your homepage looks nice, but I don't find on it the information I want - cold hard number, graphs! However, I find plenty of stuff I do not want - like twits?? I don't want twitter or anyone else to track me.

Your site looks nice, but I think we have very different goals.

Cool UI. How soon till you support all the coins that CoinMarketCap has?

We already have that data. We don't show it because we want to filter out bad data!!

Let's take an example: illiquid coins, like for new forks.

Look at the prices quoted on every exchange: you will often see huge differences. Because on some exchange, you can only buy the new coins - not sell them. So the price is high. On the exchanges where you can buy and sell, the price is low.

We think that's scammy. We don't want to list these coins or that information.

We are working on ways to do that, but extending over the top 50 is not very high in the priority list. There are even coins from the top 100 we are not comfortable showing in the API. We just hope they won't ever make it to the top 50 on our frontpage :-)

Different experiences I guess. We do not require a login. You can use the API without a key.

We actually started of with the price. Our goal was to be as low latency as possible. We have all the stats like price, histograms, market cap, etc in there. Most of our infra is keeping number stats on coins and maintaining profiles on them

However, the days of price and marketcap are over. We are seeing that feedback come from larger customers. They want to see code checkins, they want to see what's happening in the different sub-reddits, they want to keep up with what the team is tweeting. All those feeds are important to give you a holistic view of a coin and the market in general.

Anyway, happy to help and share whatever we can. Feel free to drop us a note.

Marketcap is totally overblown, I agree! We talk a bit about it in our FAQ. And I'm sorry, I assumed I needed a login on your site because I just couldn't find a way to quickly send a query.

Most sites hide they API behind a login and require a key and signing a TOS. That's not public. Our public API is totally public.

I'll be happy to get in touch, because we are starting with the same goals as you: low latency, and stats.

To see what you have achieved there, can I get a sample of your raw data? Like the first 2 days of december, showing at least the bid/ask/last per exchange, per pair. More if you have more.

It should be stale enough and a small enough window to not cause problem extracting or be of much value. Any format you want is fine. You email me a link to the dump and I'll have a look.

I must say I'm very curious now.

Yes for BTC, then for something 10x that 34.36 start looking not as good. We could make an option for people who prefer regular numbers. I will add that to the feature requests.

I think I’ll look back on this day in the future and smile: At one point the crypto bulls were so bullish that they worried they wouldn’t easily be able to fit in enough zeroes for the price without using scientific notation...”

I am indeed bullish on crypto, but the decision is driven by facts, not by passion.

The fact is the price range vary too much, even in the same scale (say BTC/USD vs XRP/USD), so we decided to have 5 characters for every price.

That requires the use of scientific notation.
