21  Bitcoin / Bitcoin Discussion / Re: HONEST QUESTION: would YOU be tempted to manipulate BTC to make HUGE profits? on: May 16, 2018, 10:29:49 AM
1)
- you sell, btc goes down, you wait until it drops further then you buy cheap and resell after market corrects
- you buy, btc goes up, everybody FOMOs, you sell again

You left out the other equally likely possibilities:

- you sell, btc goes up and you lose a bunch of money
- you buy, btc goes down and you lose a bunch of money

Your manipulation strategy only works in fantasies and fairy tales.

It is so obvious that some kind of manipulation is choking the potential price increases of all cryptos.

It is not obvious to me. Can you please show me information that clearly and undeniably indicates manipulation?
23  Bitcoin / Bitcoin Discussion / Re: What wallet to use to sign a message? on: May 15, 2018, 07:11:03 PM
Can you help me in what wallet to use for I can sign a message in Bitcoin Core. I tried with addresses from Blockchain and also with addresses generated from the self Bitcoin Core and I have no could.

You must use an address that the wallet controls because the private key is needed. Furthermore, Bitcoin Core currently can only sign a message using a legacy address (an address starting with a 1).

People can choose what they want to use. That is what is most important. If most people choose to use Facebookcoin over Bitcoin, then that's the way it is. It won't stop you from using Bitcoin, so there is nothing to be concerned about.

These guys are from different parts of the U.S. I wonder how they are connected.

I bet they have Bitcointalk accounts. Does anyone here know them?

As for #2, I think that the biggest reason why newbies are prone to losing their money is that they don't understand what they are investing in. They think nothing of handing their money to anonymous strangers on the internet simply because anonymous strangers on the internet told them to.

Just stumbled upon this thread, I assume that you're based in the States and would want to transact in person there, are you in any particular rush or having held this for so long are you happy to wait a few months for an offer higher than 115BTC?

I'm presently traveling for a few months and leave my BTC on Ledger Blue wallets in bank's safety deposit boxes, ideally my next visit to the States wouldn't be until January 2019.

I am in no particular hurry, except that the high BTC goes, the harder it will be to sell it.

Still for sale John? I can get you 115BTC

Yes, it is still available but I am asking 125 BTC. I have no reason to sell it for less than I can get by peeling it. I'll send you a PM.
30  Economy / Goods / Re: 🛑 Will I get scammed or not? Can you answer with the info I have? 🛑 on: May 09, 2018, 06:58:53 AM
It is pretty obvious that it is a scam for all the reasons people have stated. You want to believe it is legit and you are trying to convince yourself that it might not be a scam, but it is a scam. Move on. There is no opportunity here.
31  Bitcoin / Bitcoin Technical Support / Re: Can a HD XPubkey be obtained back from a derived public address? on: May 03, 2018, 05:41:50 PM
Suppose I have an HD public xpubkey and I derive bitcoin public address(es) from it.
Given one of the public bitcoin address derived from it e.g. 1F1tAaz5x1....
Can you get the xpubkey e.g. xpub6DKUi1BvKEgn...
I thought it is impossible, but someone I know claims it is possible.
And if it is possible isn't the privacy compromised in this situation?

Not sure if this is directly related but also take a look at
Deterministic Wallets, Their Advantages and their Understated Flaws ("An Understated Problem" section):
https://bitcoinmagazine.com/articles/deterministic-wallets-advantages-flaw-1385450276/

You cannot derive a key (public or private) from an address because an address is a hash (plus version byte and checksum).

Perhaps you are confusing that with a different issue: you can derive the master private key from the master public key and a child private key.
32  Other / Beginners & Help / Re: Blockchain Hash is it possible to repeat it again on other Block? on: May 03, 2018, 08:27:03 AM
If i remember correctly, this is one of the checks a node does before accepting a block... If the hash of a new block is the same as the hash of a previous block, the new block will be rejected...
Source: my memory... Might not be 100% accurate Wink

EDIT: do realise the odds of a collision are incredibly small

While the odds of a collision are extremely low, they rise with an increasing difficulty. And since the number of blocks is unbounded, the probability of a collision occurring at some pojnt in the future is 100%.

I don't have any good pictures of it. It is in my safe deposit box. Here is a cropped image of the box's inventory. Bonus points if you can identify what it is resting on.

so if you believe in HODL it is just a 'heavy' paper wallet with a private key on it Smiley Stick it in a safety deposit box...
(man, there are worse problems to have but yours...indeed!)

I do keep it in a safe deposit box, but here's the real problem: It doesn't make sense for me to own such a valuable item that just sits in a safe deposit box. I would rather have the BTC in a wallet so that I can spend it if I need to.

This is something that someone like Tim Draper or the Winklevoss twins, or even a few people on Bitcointalk, would own. They have thousands of BTC, so owning a bar worth 100+ BTC would make sense.
35  Economy / Collectibles / My loaded 100 BTC Casascius Bearer Bar on: April 15, 2018, 02:28:52 AM
Many years ago, I bought a loaded 100 BTC Casascius Bearer Bar. Now, its value has gone up so much that I no longer feel comfortable holding it.

The first bits are 1Gop7ok6. It is version 2. I don't have any good pictures but I will take some if there is interest.

I don't want to peel it, but I don't know anyone that can afford to buy it. Is there anyone here might be interested in buying it?

Some stats from uberbills:

143 100 BTC Bearer Bars were made.
91 have been peeled.
11 were opened last year.
1 has been opened so far this year.
There are only 52 left (12 are v1 and 40 are v2).

Also, 1344 Casascius coins and bars were opened last year. 357 have been opened since the beginning of this year. They are getting more and more scarce.

I’m looking for some factory sealed, older versions of the ledger hardware wallet:

Can. Not. Resist.

I'll take a pack.

BTC sent. PM sent.

Crap. I wish I could have resisted long enough to find out how much shipping will cost.

I am interested in this set. I sent a PM.
