First, I would read the news. I've already accepted my original buy-in as a sunk cost, so there's no reason to panic before understanding the situation.

Depending on what sort of news it is, I'd do one of the following:
1) If holding bitcoins is going to be criminalized in a way that has actual teeth, I may delete my wallet, or else give the coins to someone who lives in another country.
2) If it's a catastrophic protocol failure which will make Bitcoin unusable starting immediately, I probably can't get my coins onto an exchange anyway, so I'll just keep them around as a keepsake.
3) In basically any other scenario, I'd buy like mad.

Where are you in California?

How heavy is the equipment?

The offer ITT is the best thing price/performance-wise on the open market right now, but 200 coins is a lotta dough.

Edit: Would you accept in-person pickup? Depending on a couple factors it might be easier than traditional shipping.

One more bump.

The hatcher that is selected and the vote (yes or no) are handled by the client software.  The actual wallet holder has no control over this at all.
That's meaningless from a security mindset. If it's open source, people can change the client software, heck, even if it's closed source, people can change the client software with enough effort.

If you were to grab the source and modify it to always vote yes, then even if there were only 100 other voters in the system, you vote can only skew the vote by 1%, which isn't enough to cause damage and will only push up the vote threshold over time.
So now we're back to "what magical algorithm are you using to stop Sybil attacks?"

How do you force people to choose their hatchery randomly? Is there anything to be gained from choosing a hatchery on purpose instead of randomly?
286  Economy / Speculation / Re: Low volatility on: May 30, 2013, 05:24:26 PM
Three thoughts:

1) "Low volatility" compared to historical USD/BTC fluctuations isn't necessarily low compared to other markets.
2) "Invest your bitcoins in something more volatile" is only an argument for BTC if those more volatile assets can't be easily traded directly for national currency.
3) Being less attractive to speculators isn't necessarily a bad thing if it means you'll be more attractive to businesses.

or just put out the right nonce for any single hash.
There's no such algorithm.

The best hash-breaking QC algorithm halves the effective number of bits. For most uses of SHA-256 that's a big deal, but for suitability as proof-of-work it's basically irrelevant. There'll be a huge difficulty adjustment and we'll get on with our lives.

The scary thing in QC for Bitcoin is being able to break peoples' private keys.
288  Alternate cryptocurrencies / Altcoin Discussion / Re: ZenithCoin (ZTC) Proof of Work on: May 30, 2013, 02:10:08 AM
Multiple proof-of-work algorithms.

SHA-256, mergeable with Bitcoin.
Scrypt, mergeable with Litecoin.
And N additional algorithms at your option.

Give each a separate difficulty, adjusted to make it constitute 1/(N+2) of the blocks mined.

That way, if one of the PoW algorithms gets broken by an attacker, it's not enough, in and of itself, for them to successfully double-spend.
289  Alternate cryptocurrencies / Altcoin Discussion / Re: Attention present and future shit coin devs on: May 30, 2013, 12:56:24 AM
Okay, so in principle I think I agree that "Satoshi client with the constants/PoW function changed" altcoins are completely useless money grabs, and we've had way too many lately.

But...
It does not matter what your coin is called, or what "New features" you think it has.

[...]

You are all missing 1 important step, in releasing your shit coins. Market Research. Is there a market, for your coin? Do people want your coin? Well, here, let me do the market research for you. No, there isn't. No, they do not.
...if this is true - if every altcoin, no matter what new features it has, is marketless - well, that's a real shame.

It means we'll never see a blockchain that supports the Zerocoin anonymization protocol. It means we'll never see a blockchain with asset minting support, or any of the other incredibly cool new functionality that requires new opcodes which the Satoshi client devs consider bug risks.

That'd be a real shame.

LTC has been gaining ground on BTC since its inception and has key technical advantages
What advantages are those?

I seriously want to know.
291  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 10:55:29 PM
OMG you are totally missing the point.

The point wasnt to say that Litecoin is better than Bitcoin.

My point, now follow carefully, is the Litecoin allows Bitcoin to do something it couldn't on its own (by itself). This is true when exchanging in person BTC for cash, silver, gold etc. but my point is that Litecoin's properties being similar to Bitcoin's gives it that edge in terms of transferring value long distances.

Bitcoin needs something to exchange for. But if you are just trying to obscure authority then anything of value traded for BTC in person will accomplish that. Bitcoin does not have this feature on its own.

I guess what your motive for what you trade for comes into play. If you want to be able to transfer wealth across borders constantly then LTC or another secure crypto is the way to go with using Bitcoin. But if you just want to convert bitcoin to real goods without taxes then that works too.
Let me see if I understand.

Litecoin is valuable because it's something you can buy/sell for bitcoins that has all the same properties as bitcoins?
292  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 10:42:52 PM
Still traceable. I still know that both new addresses had coins sent to them from a "known" owners address.
And it's the same with Litecoin!

Frank and Helen want to break the chain of ownership. Frank controls address A with money and a new address C. Helen controls address B with money and a new address D.
Whether they're trading bitcoins for bitcoins, litecoins, BBQCoins, colored coins on the Bitcoin network, whatever, as long as they're both objects on a public blockchain, the information possessed by an attacker is:
A transferred coins to D.
B transferred coins to C.

Unless there's some other use for litecoin here, it has added nothing in terms of security or safety.

Yes you are right but to say that you can do the transaction without being traced only using bitcoin is flawed. You need something to trade otherwise trading btc for btc makes no sense.
Then trade for gold rounds. Trade for literally anything physical. None of that stuff is on a blockchain. That still gives data miners less information than trading LTC for BTC.
293  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 10:24:54 PM
WRONG: Trading bitcoin wallets is stupid.

User A can just keep a copy of their wallet and then sent the funds shortly thereafter to another bitcoin address thus screwing user B. Try again  Tongue

Yes trading fiat in person is true...good point. But problem with fiat is well it is paper and backed by bullshit. So it isnt a bad medium for paying for bills etc or getting cash off of an exchange without tax implications but it isnt the best medium to stay in based on its flawed fundamentals of devaluation to 0.
Then in-person mixing - A sending coins to a fresh address owned by B, B sending coins to a fresh address owned by A.

Or in-person trades of BTC for gold rounds.

The point is that there are a lot of ways to break the transaction chain that are just as good as BTC/LTC trading, and that don't have any requirement of a whole separate superfluous currency with identical properties and features to BTC.

If the LTC developers were to implement some more interesting features (the zerocoin protocol, for example), that'd be enough to get my attention. But as it is now? Nah.
294  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 10:12:03 PM
Say user A and user B want to exchange bitcoins for litecoins off exchange.

How do you prove that the coins sent from bitcoin wallet A to bitcoin wallet B are in fact related to the Litecoins from LTC wallet A and LTC wallet B?

This is the example I think I meant to use.

As far as I can tell you can't do this with Bitcoin alone. You can track every transaction on the block chain. But if you ahve two chains and you exchange off of a central site (literally off) then you cant prove certain bitcoins were related to certain litecoins in a P2P transaction or sorts.
If two people, offline, agree to trade Bitcoin wallets, it does the same thing.

Heck, you can do the same thing by trading national currency for BTC on localbitcoins.

Don't get me wrong, I think altcoins are super-important for a few different reasons. But I don't think Litecoin, specifically, is really that useful when its feature set is basically identical to that of Bitcoin.
295  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 09:58:26 PM
If I own Bitcoin address A and B and Litecoin address C and D and I am an exchange.

User E sends Litecoins to address D but I credit his account in my accounting system with address C litecoins (meaning if he withdrew them it would come from that address).

But say user E sells LTC for BTC. So now his balance shows up as bitcoins in the accounting from account A but when he withdraws simple send him bitcoins from account B.

So is that not enough obscurity to say that bitcoin can't do this on its own?

Or did I miss something? (sorry a bit tired, may have overlooked something)..

 Smiley

To trace the transaction you would need the exchange accounting information as well as bitcoin and litecoin block chains. Quite a bit of information when tracking I think.
I deposit some BTC at Mt. Gox, do some trading, withdraw some BTC from Mt. Gox. To trace whose coins those are, you need Mt. Gox's records, plus the Bitcoin blockchain (trivial to obtain).

All that you add by involving Litecoin is the requirement of a second blockchain (equally trivial to obtain).
296  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 09:37:52 PM
Note: Litecoins allow you to obscure the bitcoin network in terms of tracing where a transaction came from and went to. Bitcoin by itself can't do this. This is something Trace Mayer mentioned and agree with.
The Litecoin blockchain is just as public as the Bitcoin blockchain.

If you mean that I can exchange my BTC for LTC, and then my LTC for BTC, well... that's no different than manually mixing with someone else's BTC.
297  Alternate cryptocurrencies / Altcoin Discussion / Re: Will LTC make it or BTC be the lone king? on: May 29, 2013, 08:58:00 PM
I do feel its got an advantage over BTC on a technical level
What advantage would that be?
298  Economy / Goods / Re: [WTS] Tony Romas / Applebees Giftcards (4-10% Discount) on: May 29, 2013, 06:43:04 PM
Bump from the second page. Current price of a $50 giftcard is only 349 minicoins (0.349 BTC).
299  Economy / Speculation / Re: Who wants to share some bear? on: May 29, 2013, 04:16:22 AM
Thanks for sharing Smiley Very interesting to hear how you also look at your different parts. Has your gut been mostly right or wrong in the past? What about your intellectual side?
My intellectual side has thought the same thing since about March 2012: long-term confidence in the technology, short-term the only sure thing is massive volatility. That's not much of a contention, but it's proven fairly accurate

My gut has been on a roller-coaster, especially since January. During the run-up, there were times when I said to myself, "you'd better buy in, 'it' is finally happening!" There were other times that I said to myself "it's gotta crash soon, cash out while you can!" In the end, aside from one impulse buy around $120, I silenced these instincts - in any case they failed to call the top and seriously misread the crash several times - and stuck to the plan, which has been slowly but surely making me money since I bought in over a year ago.

(This is not why I don't trust my gut. I don't trust my gut because even in the best case it works without me understanding why, and without any guarantee that it'll work again tomorrow. In a zero-sum game that most people play emotionally, an emotionless, tested strategy is how you win.)

Its really cool that youre selling these giftcards at a discount price, are they cheaper than getting them through gyft?
I don't know Gyft's prices. I checked out their website but it seems everything is gated behind either "install our app on your phone" or "connect with a big social networking site". That'd be more reasonable if I was actually wanting to buy something from them, but it's a lot of identification to give out just to satisfy my curiosity.

You should also consider opening a store on www.coingig.com and build up your reputation, we also provide an escrow service that helps the buyer and the seller.
I'll consider it. 2.5% fees seem like a lot to pay for something with single-digit profit margins, though, especially since it's higher than BitMit (your better-known competitor).
