It seems like I really should have that coin graded, as it's in such good condition.
I just don't trust ANACS that much, shipping internationally uninsured, they didn't even answer my mail..

I would need some trusted user in the US who does the ANACS stuff for me, and would -after selling it- send it to the buyer as well.

The very first coin Casascius produced, the 2011 "1 Bitcoin", first series, had a spelling error in the hologram. It says "casacius" instead of "casascius". The second series and all other coins have the correct spelling.
Some people say this makes the first series more valuable, comparable to stamps with printing errors. Fact is, all first edition have that error, and those are special and rare by themselves already.

Ente

Absolutely nice work, well done!

Ente

Bid price lowered to 3.9 bitcoin, before throwing this casascius coin at ebay.

Ente

That's some good hints, thank you!

I found some websites collecting royalty-free cliparts and images:

http://www.clker.com

Especially the first one seems pretty useful.

Bump!
Don't miss out on this opportunity!

Yes, noone is forced to use/trust an escrow, as ridiculous this sounds to me.
But everyone who bids in an auction where an escrow is stated in the auction rules, is bound to this.
Else it's a breach of contract and a strong sign for a scamming attempt.

Ente

Yay, my second reference! Thanks, justbtcme.


Gave you and notserp an explaining positive reference for this.

Ente

Are you honestly telling me you want to buy what you bid upon, and stick to the rules you agreed upon in the auction OP?
Feel free to explain what other motivation you have for your (constant, as it seems) behavior.

Ente

No deadline yet, I'll leave this open for a few days.
Would you prefer to have or not to have a deadline?
After bids come in, I'll set a reasonable deadline, which should be in everyones interest too I guess.

I will hold a presentation end of May, so it's time to work on some slides.
I bet dozens and dozens of presentations about cryptocurrency were held already, most slides created from scratch.

Let's collect media useful for slides!
They should be in the public domain, which won't be a big problem with the community's spirit.

I found some places with general Bitcoin logos:
https://en.bitcoin.it/wiki/Promotional_graphics
https://bitcointalk.org/?topic=1756.0
https://bitcoin.org/en/press

Is there more out there?
Stuff like:
- an image of a centralized network and a mesh/p2p network
- a nice visualization of a chain consisting of individual blocks
- the bitcoin-release graph up to the year 2140

Also, there were several huge and nice infographics already. Maybe some of them are public domain, so we can borrow parts from there?

Of course, some catchy quotes like on
https://bitcoin.org/en/press are always good!
I will use the "Bitcoin is ratpoison" quote, from "Buffets right hand" in my presentation :-)

Either way, I'll add to this when I find more.

The winning bid turned out to probably be a scamming attempt:
https://bitcointalk.org/index.php?topic=600223.0
This coin is again up for sale.

Starting bid, again, is at 4.6 BTC.

Ente

What happened:
I held an auction for a "2011 Casascius 1st edition coin".
Justbtcme bid 5.0 BTC via PM, which was the winning bid.
He asked me to send the coin first. Refused any escrow, "I don't trust them". Didn't accept any of my various compromise offers, didn't make any reasonable offers himself. Then stopped giving any meaningful replies at all.
The original auction OP clearly said that an escrow is to be used in regular cases.

No funds were stolen, so I can't prove 100% that justbtcme is a scammer. On my opinion this does, however, warrant a public warning.

This is now resolved.


Edit on 2014-08-07:

After talking with justbtcme via PM and this thread, as well as reading what other business he is up to, I no longer believe he is -or tried to be- a scammer. He only backed out of some trades. Which is annoying, but not scamming. I am confident that he takes his business more serious now, and that this unnecessary drama will not repeat. Him doing quite a lot of successful trades is a good indicator for this as well.
I am leaving this thread alive for transparency reasons that this is resolved, not as an ongoing warning.
I am in friendly contact with justbtcme. I would sell to him again, would I have more coins to sell at this time.

Ente

How much time was between you putting up a hidden order and the "reaction"? Was your hidden order bought/sold into?

Ente

..and the winning bid is 5.0 BTC over PM.
Congratulations!

Thank you everyone for watching.

So the online computer has all necessary info, passwords, certificates, to connect to the 'offline' computer and have the transaction signed? With no human interaction? This sounds like a completely online system for me.
Yes, you wrote about 2FA. It might be safe when you do all of this right, including having things in mind like MITM- and replay-attacks.
The point about "cold storage", "offline computer" and "airgap", is, well, the non-connectivity to any other system besides the operator sitting in front of it ;-)

Ente

24h left. Make your bids, gentlemen!

That would be a very handy feature!

You can close unused swaps when clicking on the blue tab. Then a list opens, where you can close individual loans. If you only have one fat 100BTC loan, it's more complicated to close a part of it. Ask here if that's the case.

Yes! You then automatically take the cheapest loans/liquid available, both from fixed and variable rates. When you reserve swap yourself, you can regulate better what loans exactly you use, but it's not mandatory.

All three wallets are completely independent from each other. Margin stuff only happens in context of the "trading" wallet. This separation is strict, so you won't be using funds from other wallets, and will take loans instead.
When you do "margin sell", in your case with funds in the "trading" wallet, you still take up loans and work with borrowed money. If you want to avoid that, you should use "exchange" and not "margin trade" :-)

You won't see directly what offers are combined into one line. You can use http://charts-bfxdata.rhcloud.com for more info.
When you want only the 7 days offers, you simply enter "7 days" as lending time. The shorter ones will be ignored, the 7 days and longer ffers will be taken - all at 7 days length.
Your workflow will depend on what your priority is. If you want to always have the maximum length that is offered, you more or less have to pick up each offer individually.

I'm not sure if I understand exactly your scenario. I would guess this would close your position, and buy/sell at market rate to level out your books?

And, as always, people here suggest to start with small amounts, play around, explore, and learn the behavior of the platform and the market! :-)
