> China has exchange controls

Bitcoin is irrelevant, compared to still-tolerated and massively-more voluminous alternatives, for capital controls. This is a red herring.

Bitcoin was fine until ICO promoters started pilfering from the masses. In any case, China is currently loosening its capital controls [1].

This isn’t a problem that can be constrained to China. China is just reacting first. The rebranding of this action away from fraud and towards capital controls is dishonest.

At one point all crypto had reached $160B in market cap. Not small at all and risked getting much larger.

Lesson #1: if China wants something done they will do it. No courts, no public discussion, nothing.

Don't be surprised if these execs end up in jail.

It's refreshing that a country can act this quickly even if we don't agree with the action. In many countries this would require several meeting of understanding, a dozen committees forming sub-committees, accusations of corruptions and biased interest and several related court cases, and endless other shit. IMO it's actually a very smart move, to ensure a fair and complete dissolution, and if those execs dont have the bitcoin to distribute back to participants (i.e. they've been speculating or liquidating client BTC) then they're going to jail. China doesn't want the egg on face that Mt.gox / Mark Karpeles caused.

I'll remind you of how refreshing it is when I drag your family off the gulag without warrant. Its not "refreshing", its scary.

First off - no one has been dragged off, they are merely preventing the exchange operators (that are originally resident in China anyway) from leaving the country until they execute an orderly shutdown. i.e. No holidays for now, we don't want you doing a MarkK. Also, we are talking China here not NK, but don't let the facts get in the way of your point. Btw, you do have "temporary injunctions" in other parts of the world too.

That may all be true in this instance, but previously, executives have been executed for various things. The story I recall was some sort of fraud, but who knows what the real reason was. I don't have a reference handy unfortunately.

you're espousing the benefits of autocratic control. I am describing the trade-off. Sure, maybe China isn't dragging people off to gulags today but the point is that autocratic control means they can if they want to.

Once you really consider that idea a bit more you may realize it's actually the exact opposite - it's refreshing when a powerful country can't move quickly, can't get anything done fast, and has tons of gridlock due to differing opinions combined with strongly institutionalized laws and procedures. Human beings are terribly whimsical creatures, and institutions that prevent us from acting on our whims and instead force us to go through a thoroughly deliberative process are one of mankind's greatest inventions.

Thank-you for illustrating the reason we have elected, republican governments in the west and in addition have a non-popular voting system for the president in the United States(I don't mean the party of the same name, I mean the style of government).

Despite the horrors history will offer up, we as a species continue to fail to comprehend the danger of a government unrestrained by its populace. We somehow think that we will create a government that can "move fast" but not abuse its capability to do so while we are proven wrong time and time again. Thus, limited governments ever suspect by their populace are necessary to ensure opinions as illustrated above do not come to bear...

How is it irrelevant? You can buy Bitcoin with yuan, transfer the bitcoin to a foreign exchange, and then buy another currency like the US dollar with the bitcoin, thereby circumventing capital controls.
Re:China Bans Bitcoin Executives from Leaving Country, Miner... by JumpCrisscross on Wednesday September 20, 2017 @01:25AM (#15291051)
> thereby circumventing capital controls

You can also invoice hundreds of millions in fake orders. This is how the bulk of exfiltration occurs.

Addressing the rounding error before the bulk means other concerns are at work. I am ignoring, in this argument, that recent policy—preceding these orders—calls for more capital export, to keep down the yuan.

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by dannyw on Wednesday September 20, 2017 @01:40AM (#15291095)
The difference I think is that bitcoin allows someone with no connections to bypass capital controls. I'm not saying bitcoin isn't a rounding error, I'm sure other priorities (like ICO scams) are at work, but that might be another point.
Re:China Bans Bitcoin Executives from Leaving Country, Miner... by jogjayr on Wednesday September 20, 2017 @02:43AM (#15291325)
But someone with no connections would presumably not have that much capital to move either, right? They'd not move much volume even if they bypassed capital controls.

It can be dangerous though. If suddenly several million citizens start transferring small amounts you can easily get outflows of several billion USD a month. Done by a few that would be an amount easily noticed.

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by rblatz on Wednesday September 20, 2017 @01:53AM (#15291146)
You could mine, even if it was unprofitable. Spending 10 million in mining costs to produce $5million in bitcoin is still a win for a lot of people trying to move money out of China.
Re:China Bans Bitcoin Executives from Leaving Country, Miner... by lifeisstillgood on Wednesday September 20, 2017 @03:57AM (#15291610)
Does that work - I think the mining reward is 25 BTC, about 75,000 USD. So for 7.5million thats being the winning miner 100 times.

I honestly don't know what setup it takes to be reasonably certain to be the winning miner these days - does anyone have stats on how many miners and how often one might be expected to "win"?

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by lmm on Wednesday September 20, 2017 @05:26AM (#15291938)
The stats don't really matter, because the market is designed to equilibrate the price: it costs 7.5 million to mine 7.5 million's worth (in expectation, net present value and all that), and always will. If you're worried about reducing your variance you can join a pool rather than mining directly.

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by lmm on Thursday September 21, 2017 @11:05AM (#15304143)
At a guess we'd be talking 6 months - 2 years - my vague memory/impression is that's roughly the timescale on which mining hardware goes from new to worthless. If you're more vertically integrated in terms of buying datacenters/chip fabs/what-have-you then I'd imagine longer.

You can mine in a pool that distributes the pool's winnings proportionally to hashpower to its members. You don't need to actually mine any blocks on your own.

China breakdown on exchanges has begun before the ICO rage. Top exchanges did hold crpyto withdrawals for all their users for a long period of time (several months).

I think it is a little bit of 1. China understanding the risks posed by bitcoin capital flight and 2. bitcoin turning from a small community to $100bn+ market thing.

Needless to say this is about all crypto and not just bitcoin.

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by peoplewindow on Wednesday September 20, 2017 @10:26AM (#15294054)
There's also the rumour that the exchanges are fractional reserve to a huge extent. I suspect that plays a role.
Re:China Bans Bitcoin Executives from Leaving Country, Miner... by vkou on Wednesday September 20, 2017 @11:34AM (#15294898)
Exchanges can't operate on a fractional reserve principle. Fractional reserve works for banks because:

Cash on hand + Money people owe the bank >= Cash bank owes its customers.

If an exchange is operating in such a manner, this means that:

Cash + BTC on hand < Cash + BTC exchange owes its customers.

We don't call that a fractional reserve. We call it insolvency (And knowingly accepting new deposits in such an exchange is called 'Fraud.')

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by Animats on Wednesday September 20, 2017 @01:31PM (#15296238)
Well, we're going to find out very soon. As the Bitcoin exchanges in China shut down, they're going to have to pay back all their customers. "Platforms should also tell the government by Wednesday Sept. 20 how they will allow users to make withdrawals in a risk-free manner and handle funds to ensure that investors' interests are protected."[1]

The executives of the exchanges were told not to try to leave China. Somebody foresaw this problem.

ICOs are a perfectly valid way to raise money. In fact, as long as you don't raise more than the cap specified by Reg CF ($1,070,000), it's no different than crowdfunding.

I predict that future startups will probably have a small ICO that is covered under Reg CF, and then a bigger token sale under Reg A.

What do you think is easier to accomplish?

A technical white paper that doesn't bs with buzzwords, or a business plan filled with marketing fluff?

Think about it. You could spend hours working on a business plan that nobody will ever read. With the ICO route, you can reach an audience like never before.

> A technical white paper that doesn't bs with buzzwords, or a business plan filled with marketing fluff?

If you are serious about your endeavour, you should ideally do both.

If you proofed the technical side of your idea, it's good, but if you didn't try to see if their was a possibility to make it profitable, then you are not starting a business.

Who would invest in a business if the people responsible for it are not serious about it ?

> With the ICO route, you can reach an audience like never before.

An audience who can understand your whitepaper and what an ICO is is definitly not an audience "like never before".

Re:China Bans Bitcoin Executives from Leaving Country, Miner... by rblatz on Wednesday September 20, 2017 @05:19AM (#15291907)

>A technical white paper that doesn't bs with buzzwords

You mean like this? http://infolab.stanford.edu/~backrub/google.html

I hope this shows you that I am very serious about the "idea".

But is there even a mechanism here?

---------------------------------

My issue with ICO's is that there is neither a mechanism (in fact it's explicitly barred by law) or even an expectation for a company that executes and becomes profitable, to "repay" the people who bought into the ICO, by repurchasing at a multiple.

In other words, if you raise $1 million on coins, the expectation is that if you use it to become a profitable company, you will not rebuy any of those coins.

In financial terms here is what is going on when you raise money for a white paper using an ICO.

You're in two markets: you're in the market of selling collectible, limited-edition playing cards with cool branding. Theoretically you don't really care about the market for them, because selling playing cards isn't the business you're "really" in. The cards don't represent shares in your company. They just happened to be called Virtual Shares Collectible Playing Cards. And you sell them because you're trying to raise money. The "cooler" your white paper, the cooler the cards. The "real" business is just branding for the collectible cards. But what happens later to the cards has no relation to your white paper / real business. They're separate entities.

Separately, you use whatever funds raised, to fund whatever you wrote about in your white paper. There is no promised or expected flow back from the second to the first thing.

It is literally illegal to do an ICO and say that if you become a profitable business, you will repurchase the coins at a 4x multiple to their ICO price. That is illegal.

So while selling collectible playing cards by branding them with a really cool white paper might be a great way to raise money -- and who knows, the market for them might stay strong for a long time -- it really has nothing to do with the financials of the business you use those funds for.

someone correct me if I'm wrong. where is the flow back from a successful business to the coins? They don't represent ownership. The business isn't rebuying them.

What does the success of the business have to do with the coins they're branding? Nothing, right?

This comment only got down voted because the traditional VC crowd is upset that something has come along which can disrupt their tight funnel which gives them a monopoly on venture capital and the corporate acquisition pipeline.

My open source project is now receiving funding/sponsorship from a cryptocurrency company.

I had applied to Y Combinator and various incubators in my country many times over the years but was consistently rejected because VCs didn't understand what I was doing - The founders of many of these cryptocurrencies (especially the more popular ones) actually understand technology very profoundly and so I am having much more luck there. I think that some cryptocurrencies are literally 'smart money'.

>> Pilfering from the masses.

Whenever big corporations drain resources from the masses and keeps them enslaved by essentially brainwashing them; somehow that's OK. But when something comes along which offers the masses a chance for a quick (obviously high-risk) escape from slavery, that's a scam?

I don't agree with how bureaucrats spin this; as though people need to be protected from themselves. Maybe the government should ban entrepreneurship too - that's very high risk and very random/unpredictable too.
