Bump.

I have a colleague who's setting up a regional crypto exchange. All the competitors are pretty shitty, even by crypto-exchange standards. So the goal is to beat all the competition in terms of technology.

He's looking for a white box solution. Ideally something that supports a real limit order book matching engine, and something with a decent push-based datafeed. It'd have to support localization in the frontend, both for the language and the exchange brand.

Anyone have any recommendations here? Feel free to either respond here, or drop me an email. Thanks.

Maybe this:

Out of curiosity: what would be the advantage of you colleague compared to others? If it's about being "less shitty", why don't people use GDAX, poloniex...? Or is being local a must?

Does anyone find any value in this sort of research and especially the work of Sornette?

Serious question: I personally don't, but I'd be glad to hear other opinions.

My point is that when I see people like Sornette predicting market crashes with very vague statements like "in the following months"
(e.g. https://www.valuewalk.com/2017/07/financial-crisis-observatory/)
and then months later the S&P500 market is up+20% from where it was at the time of Sornette's prediction, and even now, after some correction, is still +5% higher than at the time of Sornette's prediction...

I guess if we wait forever, sooner or later Sornette predictions will somehow come true, a bit like Nostradamus, correct?

@kloc

Thanks for the recommendation.

A lot of factors behind why GDAX, et al. isn't competitive in this region. Poor localization. No support for the local fiat currencies. The banking systems in this part of the world are often subject to capital controls and/or poorly integrated. GDAX doesn't work with the dominant regional payment systems. Plus the would-be exchange already had a pre-existing forex brokerage, so it already has a well known brand.

Thx - brand and banking/capital reasons make a lot of sense.

Localization - I guess this is somewhere in central or SE Asia...?

@TSWP
Like in "practical usage"? No. I doubt this method has any value outside of its classical usage in material science.

I do like the idea that an extreme event might be more predictable than everyday business.

But this stuff has way too many parameters for a tiny set of data...

Yes, that is what I did mean:

separating "academia" from "practical usage".

Glad to know you agree.

Sometimes news tell that large BTC holders are dumping it, therefore, price goes down.

Bloomberg

Is it possible to check what share of BTCs are changing hands and which fraction is "sleeping"?
That would give an ultimate answer to claims made by press.

It looks like some crypto exchanges use AWS facilities since inter-temporal structure between them is almost flat.
Seeing it I suspect that Satoshi is Bezos...

GDAX is on AWS, which always cracked me up.

It's pretty obvious in hindsight that Satoshi was actually Hal Finney.

Another one (accidentally came after analysis):
"BitMEX systems take advantage of Amazon Web Services’ world-class security."
.
Satoshi thing was a joke. Hypothesis about Finney is most likely true.

The situation when competing exchanges process billions working inside ASW is funny.

Collapse was beautiful. Same effect as CB intervention.
Somehow it started days before USD-EUR move.
Is there any link?

My conspiracy idea is that someone with knowledge about upcoming depreciating dollar has moved assets out of BTC and injected into leveraged dollar deal. The rest was just following panic.

Another idea is about Miners' World War - II (first happened back in mid 2011)

I suspect some tax loss harvesting contributed to the selloff, even though bitcoin-people are not too much into tax stuff... But I wonder what gains these losses would offset, as it has been a pretty crappy year for investors generally.

For investors perhaps, although not exactly since write-offs of losses are traditional way to offset taxes.

For miners yes. Look at hash rate decline. Below $3000 the sell-offs BTC will accelerate.

However, this jumpy dynamics (seen at both, macro and micro levels) looks very much as manipulative.
One thing is good - volatility. Option prices jump !

Why do you see acceleration of the decline below $3000? How does that affect mining, and why is $3000 the magic number?

It is a guesstimate based on:
1. historical lookback which has its own psychological and symbolic impact. 3000 was a last minimum achieved at 15SEP17 when everyone bashed BTC including famous J.Dimon statement that BTC is fraud.

2. pricing structure of mining companies, where they experience losses at levels below 3000. Small miners, less optimized, experience losses already, such as householders.
Example of today:
Break-even is achieved 14Th/s, 5 cent/kWh and BTCUSD=2600 (but there are other costs like price of device, personnel, legal risks, etc!)
https://whattomine.com/coins/1-btc-sha-256?utf8=%E2%9C%93&hr=14000.0&p=1370.0&fee=0.0&cost=0.05&hcost=0.0&btc_enabled=true&btc=2600.0&commit=Calculate
It is like power plant - once your production goes under water, you start selling assets to maintain production and market share.

3. unclear policy of big miners, especially of the one who is Unknown. These guys are aware of above gaming rules.

4. I also personally do not rule out a possibility that BigMoney are looking to enter the market and startup new bubble.

Disclaimer: I made these links non-clickable on purpose, such that you see yourself where you going to. Crypto space is still quite infected.

Why the miners will want to be exposed to the additional volatility related to the price change? They probably unload inventory as fast as possible. If someone is speculating I think it's not related to the mining itself.

Not true. Most miners including the big one are genuine believers into BTC.
I know few of smaller scale, they suffer because selling BTC for them is like "end of everything".

Besides, one can buy puts to protect asset value or futures to hedge exposure.

Everyone said the first 2018 selloff in March or whatever it was had something to do with tax surprises. Much more likely IMO.

My favorite zerohedge tier speculation (which is a little more than a speculation): man, Tesla's shares are doing remarkably well all things considered.

True.
To add my sentiment: I believe it will go up-up-up through deep down. That's why I buy volatility.

One of early BTC investors (hodlers) said: "after buying BTC at 1$ this is the SECOND top collapse I have seen. There are quite few more in front of us."

it's announced that Ethereum Classic team has collapsed due to funding problem.
Likely, it is the third (forth, whatever) reason of recent collapse - cleaning up crypto coins landscape.
