I am an iMBA degree student at UIUC. I took a leap of faith and got admitted in the iMBA program (Jan'17 cohort). I can say with confidence that UIUC is not only the first one to give such an affordable education but their online education platform is pretty stable.

Lots of my friends who are in the iMBA program are pretty serious about the Masters in DS. They had to be, after all they are getting 2 masters degree for half the price. I might be wrong but Berkeley is offering their DS Masters (online program for 100k+)


That’s through Coursera or the university directly?

It looks interesting but I’d have to qualify for federal financial aid to do the program and trust the university more than Coursera.


I never want to reuse my comments from other thread but this time I just can't resist. No one really anticipated what we all are currently experiencing and Coinbase is not different.

It seems Coinbase struggling to cope up:

$0000 - $1000: 1789 days

$1000- $2000: 1271 days

$2000- $3000: 23 days

$3000- $4000: 62 days

$4000- $5000: 61 days

$5000- $6000: 8 days

$6000- $7000: 13 days

$7000- $8000: 14 days

$8000- $9000: 9 days

$9000-$10000: 2 days

$10000-$11000: 1 day

$11000-$12000: 6 days

$12000-$13000: 17 hours

$13000-$14000: 4 hours

$14000-$15000: 10 hours

$15000-$16000: 5 hours

$16000-$17000: 2 hours

$17000-$18000: 10 minutes

$18000-$19000: 3 minutes


It would make more sense to put this on a logarithmic scale. The move from $18000-$19000 is nowhere near as meaningful as the move from $0 to $1000.

Also, the move to $19,000 seems to have been some kind of liquidity issue on GDAX, the price did not get that high on other exchanges.


I agree, so putting this together from the parent's info:

$0000 - $1000: 1789 days

$1000- $2000: 1271 days

$2000- $4000: 85 days

$4000- $8000: 96 days

$8000- $19000: 20 days

Edit: Even on a logarithmic scale, bitcoin is experiencing exponential growth.


Thanks, this is a really interesting way of looking at it. The change from $0-1000 is still not comparable to the other 2x gains. I looked up $500-$1000 and it looks like it took about 1000 days.


wow



That being said, does price matter or does volume matter, in terms of Coinbase? Their infrastructure should be indifferent to price. I understand there's a correlation there, but daily trading volume would be the ultimate determinant of Coinbase's performance.


This unfortunately reminds me too much of stellar evolution timetable[1]:

> Star burns through a succession of nuclear fusion fuels:

    Hydrogen burning: 10 Myr
    Helium burning: 1 Myr
    Carbon burning: 1000 years
    Neon burning: ~10 years
    Oxygen burning: ~1 year
    Silicon burning: ~1 day
(...and then it goes supernova.)

I hope Bitcoin's end is not as violent. :/

While I agree with you that the amount of users probably raised a lot to the point were servers are stressed out, there's something slightly off with the data you present: the latest entries are actually smaller percentage moves.

Here is the same data with (approximated) percentage moves:

$0000 - $1000: 1789 days

+100% ($2000): 1271 days

+50% ($3000): 23 days

+33% ($4000): 62 days

+25% ($5000): 61 days

+20% ($6000): 8 days

+16% ($7000): 13 days

+14% ($8000): 14 days

+12.5% ($9000): 9 days

+11% ($10000): 2 days

+10% ($11000): 1 day

+9% ($12000): 6 days

+8% ($13000): 17 hours

+7.5% ($14000): 4 hours

+7% ($15000): 10 hours

+6.5% ($16000): 5 hours

+6.25% ($17000): 2 hours

+5.8% ($18000): 10 minutes

+5.5% ($19000): 3 minutes

Anyway, it's more the volume that is of importance here than the price when it happens.


How much money needed to come into the bitcoin market for it bump from 15k to 19k? Where is this money coming from??


You don't need money "coming into" to increase value of Bitcoin.

All you need is back and worth trades in th market. It can even be market manipulation where some buy and sell between themselves.

Bitcoin has massive market liquidity problem. Once people want to sell, the price drops like a stone. This is why it would be convent to have "technical problems" or do DDoS attack to prevent sells and allow markets to calm.


Had to be a lot. Should have screen recorded it, but instead recorded with my phone. The order book entries and chart were going nuts. Entire sections of the book disappearing at once. The chart would go almost entirely flat several times.

Almost always you see minor movement on the order book except maybe sometimes at the actual mid point it may update a bit. The chart is almost always balanced until the past few weeks it's be HEAVILY weighed towards the sell side.

71K+ BTC had been already traded by the time it hit high 19k.


I saw the same thing. It was insane


Technically, not much. Let's say people stopped trading except for two people that made a series of trades of .0000001 btc at $100k, then the price would be $100k.


Not much. 1% of asset allocation for an institutional investor is enough for that.

EDIT: You currently need $70m to bump the market above 20k on GDAX. That's a lot for retail investors but not much if institutional investors get involved.


In the grand scheme of things sure, but definitely a large influx as compared to the size of the market in Coinbase.

We're talking probably low 2-digit millions to make big moves I think.


Yep, around $70m to get it above $20k.


What institutional investor is going to put 1% into Bitcoin?


How do you determine the $70m?


You look at the "Depth Chart" -- it shows you how much people are selling (or buying if you go to the right) in a way that escalates as you get further away from the mid-market price that is currently executing.


"How much money needed to come into the bitcoin market for it bump from 15k to 19k?"

Almost none.

If there are just a few transactions at a price, well, we assume that is the worth of all bitcoins in existence.

Which is a crazy assumption, but hey.


right now, as i'm looking on gdax, the price is 16.3k/btc, and it would take 42m to fulfill all of the sell orders to push it up to 19k. that's not a lot (but it's only one exchange). i think <100m to swing the market by that much across all of the exchanges.


New money is coming in that's for sure. But a limited resource and a lack of sellers will also push the price.


Tangent: it would be cool to have a browser extension that could notice that this data could be presented visually and offer to show you e.g. the scatter plot.


Can you describe what this data is you're sharing? As is it's not clear what phenomenon you're describing.


https://en.wikipedia.org/wiki/History_of_bitcoin

The insane rise in the valuation of Bitcoin. How many times we have seen a currency or an asset that represents this kind of momentum? Clearly no one has seen this coming (that soon).


Well, there was the tulip bubble of 1637.


I think its the amount of time taken for the price of Bitcoin to rise from the first amount to the second.


>No one really anticipated what we all are currently experiencing

Actually, those in the Bitcoin economic space have been saying this was going to happen for ~3 years

Hyperbitcoinization - Daniel Krawisz - March 29, 2014 http://nakamotoinstitute.org/mempool/hyperbitcoinization/


The article you've linked to does not address the situation being described.


How many 9s do you think Coinbase has?

2 9s, or 99% uptime? Or is it worse than that?


They are rarely completely offline. But, they've been experiencing all sorts of "minor outages" and partial service degradation. And when you can't trade or transfer between wallets, the fact that their portal is "up" doesn't matter much.


During normal times? Uptime is maybe 95-99% as they're down for maintenance for a few hours every few days, usually during off hours.

During major price swings? About 10% uptime at best. They're almost always down when the price jumps or drops.


The way things are moving it seems no one is selling and that's what baffles me. Crypto market is something we have never seen before where people are buying and not selling that is what is driving the price of Bitcoin.


Not true. For each buy that happens, there must be a sale. There are more buyers than sellers right now, not no sellers. Each time the price goes up, that's a sale _that happened_

This is something we've seen many times before. It's not new. It's a classic bubble where demand (buyers) greatly outstrips supply (sellers).

The big question is why. Crypto currencies haven't suddenly gotten more useful. The current rise is fueled by speculation of the ability to resell at a higher price.


I think a large part of the answer is scope. The scope is international, and the scope of average, retail investors and their ability to do this ... well, unprecedented. Next, you have a lot of people with a lot of cash, tens, maybe hundreds of millions of potential people, in China, Korea, Japan, U.S., Europe, and so forth.

That's my hypothesis as to the 'unprecedented' aspect to all of this.

What other bubbles are there that were so lightning-quick, vast in geography and 24/7 operation.

Tulips at least required some sort of hand waving at auctions (presumably) and some transportation at some point after 'settlement'.

This is as fast as a video game connected to your bank account.


Some people definitely are selling, it's not like we're seeing new BTC come from thin air for all these buyers (assuming they're getting BTC on their private wallets instead of an IOU that might not be covered with real BTC)

However, at the moment there's a lot of willingness to buy and little willingness to sell, and that's why the price is rising.


People are selling, otherwise there would be no market.


There can be a market with only buyers or sellers. There is just no execution.

Hardware company or Software company, we can always debate about it and choose whatever we want to say. In few years Apple will be a "Trillion dollar company" and there won't be any debate or doubt about it.


More like in a few weeks.


Now what kind of business choose to remain down for 2 hours plus during the peak business hours?

Seems cloud computing still has a lot to learn.


If interested there is a very good book about this subject: http://www.amazon.com/Fermats-Enigma-Greatest-Mathematical-P...


Ha. I've read it as "Fermat's Last Theorem" - guess that's the UK name.

For anyone who hasn't read them Simon Singh's books are great introductions to subjects by tracking their history. In this case mathematics, but he also has one about cryptography [1] and another on the space and the universe [2].

[1] http://www.amazon.co.uk/Code-Book-Science-Secrecy-Cryptograp...

[2] http://www.amazon.co.uk/Big-Bang-Important-Scientific-Discov...


Seconded, the subject matter is fascinating and the human story of Wiles' difficult journey and ultimate accomplishment is gripping. One of the books I've most enjoyed ever on any topic, let alone in popular science / maths. It's Singh's best work.


Well so many things comes to mind when thinking about this kind of guarantee. Location is one for example. If I am willing to live and work in Chicago but Udacity found me the job in Sacramento, CA will I be willing to move to CA. I don't think so and that makes me the potential candidate where my fee won't be refunded as I say NO to the job offering based on the preference of the city I choose to work/live in.


APJ once said, "the best leader when failed, take the complete responsibility of failure, and when succeed give the credit to his team - this is the best management principle i have learn for the first time"
