Dont think one exists. I know you can short on margin on sites like bitfinex.

I have never used this exchange and have no further knowledge of their operations or reputation but they offer Bitcoin options trading. https://www.deribit.com/

Use BitMEX. Solid platform out of HK

look at ledger x

Oh dear.

That is not true. Look at the chain interview on RV - with the dude from Panterra Capital, that is exactly what he is doing

ethereum. andddd you just lost all your credibilty

Don't think their he mentioned anything about Visa. Why do you mention it? Genuine q. Hadn't seen it before

...and if you're correct nothing changes for you. On the other hand if you short bitcoin now when you're scenario unfolds you'll be left with something less ephemeral than smugness.

Scaling in a centrally controlled system is easy and has been done before. Scaling while remaining decentralized is a new frontier that Bitcoin is working its way through.

Spencer Boghart. Aaron Van Wirdum.. Adam Back. Greg Maxwell. Eric Lombrozo. Peter Wuille. Andreas Antonopolous. I would add a few more. Peter Todd, Lukedashjr, WhalePanda, Riccardo Spagni, Jimmy Song. Most of the people listed are on twitter, a few on reddit, and also post on the bitcoin dev mailing list

Ethereum isnt more secure than bitcoin by any stretch of the imagination. Last i checked the hashrate of eth was 50 TH/s and btc was 5 million TH/s. and once they switch to Proof of Stake there will be no mining power behind it just a group of trusted holders.

1st August

That may actually not be a bad idea...

Would you think it a bad idea for someone at it a while to go mid july.. okay I've done very well.. lets go to fiat and see how this plays out over next month or so.. upside is little if you've been at it a while.. downside not so little?.. people have to make their own mind upI fully appreciate that just interested in your thoughts on this

It all depends on your personal situation, conviction level, tolerance for volatility, etc. Markets are pretty liquid so it should be fairly easy to get in and out as a retail investor.

That's unlikely imo, as it is an open source project. Just like with the internet protocols (TCP, IP, UDP, ...) once enough people start disagreeing over where a protocol should go, it tends to freeze into place and serve as a foundation that higher level protocols are built on top of.

think about democracy and its history. people as a collective tend not to do very well in their decision process. Bitcoin won't be an exception to that rule. It would truly be shortsighted to see it any other way.

Hi Gordon - glad the presentation was valuable! Assuming the Bitcoin core protocol freezes in place, transaction volumes would be mostly taken care of in 2nd layer protocols (which in absence of segwit would take longer to develop) such as sidechains and the lightning network. In those environments fees would range from zero (like how you can browse a web page for free as a compensation for using the platform) to higher, depending on the particular security/volume trade-offs. It's impossible to predict the price of tx on the main chain, this would depend on how much security would be reduced on 2nd layer solutions. It could be $100, $1,000 or even $10,000 per tx over time, all would be decided by the market - and no I don't think TX cost would ever be higher than the price of BTC (though 1 btc in reality is an arbitrarily chosen unit, as 1/21millionth of total supply). Also keep in mind that Bitcoin is already scaling like Nick Szabo (2009) and Hal Finney (2010) envisioned: millions of tx daily off-chain, processed by trusted entities like exchanges, gambling websites, etc.

Yeah, I was short and closed that position in December 2016 - so was a profitable trade. My fundamental concerns about ETH have changed little, even though the market is clearly excited about the platform's promises.

So basically, its just down to hype then?

@Conor: You can short CCs on specific exchanges. I guess in the background it works like any short, you borrow someone else's coins, sell them and then buy them back at some point in the future. Or an exchange might issue a CC IOU to someone that bought a coin and offset the position "synthetic" position by someone else's short. But that would probably make the exchange "less pristine"?

The blockchain doesn't work without the digital bearer asset (bitcoin), nor is there much use for it other than digital bearer assets. The people making private blockchains are selling vaporware which is less efficient than existing database tech.

Btc is certainly a high risk investment and I wouldn't tell anyone to lock it away for ten days let alone ten years. And you certainly shouldn't be doing all your investing in btc/cryto. It depends on your conditions. Worth, appetite for risk, time you are willing to monitor it(because as I said its very high risk)..

Steve....hence why the transformation from physical to digital/virtual realm is one of the most difficult to conceptualize but one which is paramount to grasp because it's happening. I can't touch or feel WI-FI internet but I know it's real, that it exists, everybody is using it and it works. As long as a utility is being utilized providing function, confidence in that network grows and it's existence continuously validated.

Thanks, appreciated. Exchanges like Kraken, Bitfinex, Poloniex have many inter-cryptocurrency pairs. E.g. ETC/ETH, or LTC/BTC, or ETH/BTC. And they offer margin trading. So even if you don't have ETH in your account, one could "sell" ETH for BTC on margin, and then later buy it back.

Hmmm.... valid point.

This "geek" is telling you the good and bad, the upcoming nuance and everything in between. He's not the charlatan you're alluding to. Also, those geeks who talked about Y2K, they also had the solution... the media however ran wild with the fear piece and used it to sell media assets instead of discussing the solution. Listen to biased news at your peril.

Back in 1989 Bulletin Board Systems were loaded with Geeks talking riddles about the prospects of the tech boom , Billions were invested ( flushed down into Apple, Microsoft and similar stock ) to "tackle the problem of getting filthy rich" . In 2017 the Geeks are back in force , listen to Geeks at your peril .

There was no Y2K solution because there was no problem , i was an engineer working in Power Generation for GE at the time and was put on alert to support clients as we entered year 2000 , there was no problem what so ever , it was all BS and billions were wasted by fools . Those Geek junkies that bought Apple in 1989 had a very bumpy ride ,it could have been bought much cheaper after the Geeks departed I predict they same for the Bitcoin bulls. Simply put if Bitcoin is such an advance why do they have to invent a new language to talk about it ?

What new language are you talking about Niall S? New terms come along with everything new. Not some bitcoin bull or anything just don't understand what you mean by the language comment?

I believe in the case of a split you would own your "old" coins on both new chains, somebody correct me if I misunderstood

In the case of a hard-fork you'd own coins on both chains forever (like with ETH and ETC). In the case of a User Activated Soft Fork (UASF), you'd also own coins on both sides, but one side would disappear if the new UASF wins over more than 50% of the bitcoin mining hash rate.

when does this decision get made? seems pretty massive. hopefully it will shake out all the "retail" traders (cough cough not us) and then we will be able to jump on the winning side at low prices. Am I naive to day this? (probably)

1st of August is an important date imo, but if the UASF doesn't get 5 or 10% of mining support from the getgo, it's likely that it'll be considered a non-event and that the Bitcoin status quo will be maintained for the time being.

Glad it was meaningful!

Intro says video recorded on June 5

I don't exactly see what your argument is. I feel you will find a lot of people on here who are bullish both compared to twitter and other channels. I personally think we need to see the next bad event (post 3k rally) in one of the cryptos to judge whether it is in strong or weakish hands. And goldbugs will naturally be suspicious about this community buying into an exponential rise and declining market share of the once 90% asset in the space.

where in michigan?
