Probably a stupid question, but from looking at a coin in a picture there is a QR code which points towards a non functioning website?
Also, how do you tell the difference between 2FA and private key Titan's?

https://krebsonsecurity.com/2020/06/privnotes-com-is-phishing-bitcoin-from-users-of-private-messaging-service-privnote-com/privnotes.com is a scam site that tricks people into thinking they are going to privnote.com ( a legit site, trusted site) Any bitcoin addresses posted in privnotes.com will be changed to a different address. Search for the wrong thing and privnotes.com will be the first result you see in google search! Be careful out there, it's similar to the online QR code generators, which do the exact same thing! In general never send to any address received in a private message anywhere, unless 100% certain you are talking to who you thought you were. Always worth checking the PGP signature as well, its a good habit, and it's not out of the realm of possibility a similar MITM attack could happen anywhere.

I assume this has been discussed a lot, I just can't find any good threads via search or google site:bitcointalk.org. If anybody could point me towards some, that would be good.
Now that coins have been circulating for quite a while, it would seem there are two risk vectors buying coins.
1) The coin creation was compromised. Either the creator could have deliberately kept the private key, or an employee somewhere involved in the manufacturing could have. This seems pretty unlikely to me for any of the main physical coins, they are all linked to crypto OG's with reputations, and if it were to happen, it probably would have by now.
2) A buyer of second hand coins works out how to compromise the hologram. This could be pretty profitable. It's also almost impossible to guard against, as the creator of the coins has to think of all possible unique attacks, while the attacker only has to think one. Or wait for technology to improve enough. And once you have one, you can slowly buy and sell your way through every coin that comes up for sale.
The only true way to guard against this to buy coins with provenance. Is there some kind of database of coin addresses that have sold through here? Ie if I know who owned it and for how long, that coin becomes worth more that a coin a newbie says they bought in 2012 and just found in their shoebox? The best way would be through slabbed coins that were slabbed before bitcoin was really worth compromising, ie a 1 btc Casascius slabbed in 2013 would not have been worth the effort back then, and if you really believed BTC would go to five figures, it would be easier just to buy it. I can't work out if the slabs are dated though? Do ANACS etc put a date on it? Or keep a public facing record? As is, can you tell from looking at pictures of a slabbed coin for sale when it was slabbed?
Sorry to post a thread that has probably come up a million times, I did try to search I promise! And I know it basically comes down to a combination of hope and trust, and bitcoin has been good enough to me that I'm going to keep buying some of it's history to put in a safe and never peel or sell, so in all likely hood I may never even know if one of my coins gets compromised, I'm just interested in possible ways to minimise the hope and trust involved. It would be reasonable easy to write a crawler for addresses/sales on this site, dates and usernames etc, not sure if it would be useful, and does seem a bit invasive. But being able to buy a coin that I could look up and see -> Sold by Smoothie in 2013. Then sold by Loaded to Minerjones in 2017. Then MJ to LesbianCow in 2019. Now for sale by LC. That would make the coin worth more, and be a cool history to go with the coin. But yeah, I could see how it could also be a privacy invading, so maybe opt-in? Or maybe this exists and I'm reinventing the wheel? Or maybe so few coins have sold it's not worth the effort? Dunno, just thinking out loud. The higher bitcoin goes, the more pressure there will be to peel to minimise risk, and I find that a bit sad.

that every bubble has been different. Ashamed to say i watched the bubble to $280 and sat it out in disbelief, despite having been interested in BTC for over a year. When it crashed back down i bought a lot as it fluctuated between 60~120 for quite a while, cursing myself for having thought about buying at $15 and just spending money on other shit instead, like gold. Great investment that has been. As this week i am back to where i was a few years ago, and only then cause of the Aussie dollar.
Fair value in my opinion for the last 12 months has been between 300 and 400, based mainly of blockchain stats like wallets, transactions, and usd volume. Still only sold 25% of my stash at $800, more because i needed the money than i had the courage of my convictions.
For the time being I still believe that is a fair price, but my gut feeling, which has no data to back it up, but has been good to me when i have listened to it, tells me BTC is at a similar place is was at $140 in 2013. ie poised to take off.
Obviously nobody should take the gut feelings of an anonymous person on the internet seriously, but I tend to take them seriously given how they have worked out in my life. The conscious mind can process something like 50 bits of information per second. Our brains unconsciously process 10 million bits of information per second from our eyes alone. The more you consciously study something, the better your unconscious brain can make connections you are simply unable to reason out.
My unconscious brain is now telling me to buy with both hands, so I am. We shall see how this all works out, yes?

As an Aussie, I have to say, all these retailers offering BTC payment are completely missing the point. Why would an American pay with BTC? A credit card is surely much much easier. It's us foreigners that need it, we get screwed by the currency conversion. At the moment the only person paying with BTC is someone that already had them, probably purchased much much cheaper, and is in effect cashing out. Nobody in their right mind would buy BTC just to purchase something online, the hassle and time involved is still ridiculous. But for something like a laptop, where currency conversion is usually around 3 -5 % of price, it could make a $100 dollar difference to everyone overseas, which would definitely drive adoption.
Dell, Overstock et al, get your shit together!! Take my BTC!!! Save me money!! Give me the satisfaction of denying Paypal their exorbitant currency conversion fees!!

Just had to buy my girlfriend a 128gb card to boost her macbook air storage. Used ebay and paypal ( newegg doesn't let Australians use bitcoins yet  ) Paypal fees are one thing, their exchange rates are another. Currently it is 0.944. Paypal gave me 0.91. So another 4 bucks on top of the fees. Bitcoin may not yet be better for lots of US customers, as you don't save anything and it can be a bit of a hassle, but for the rest of us poor shmucks around the world, getting rid of exchange rate ripoffs is a big fucking deal. I'm planning on buying a new Thinkpad this year, at those kind of rates it would be $75 dollars worth of exchange rate rip off!! Given electronics / software cost us Aussies between 20 - 50% more on average than in the US, being able to purchase from overseas and use bitcoin to avoid the exchange rate issues, it really is only a matter of time before everyone starts using it. Speculation is one thing. Saving money is another. Feeling pissed off over getting ripped off is the biggest motivator i have found yet!! p.s. bought the macbook from CoinsForTech. Awesome service. |

Ok so this is a strange one, not sure if i have missed something obvious but here it is: 3 days ago I was sending a few bitcoins through blockchain.info send shared and of the 5 or 6 transactions i sent, one of them was taking a long time to arrive. I wanted to buy something so I went ahead and bought it from the wallet the coins were going to be sent to. The last sendshared (3.81BTC) never arrived......BUT the last transaction, the one i spent, was for 18.1 BTC. However when i search blockchain.info, it shows that last transaction as being for 14.23BTC NOT the 18.1BTC i sent. Now if you add the missing 3.81 to the 14.23 blockchain has as outgoing, you get 18.1BTC (including fees etc). The thing is though, the wallet in question shows 18.1 BTC as the outgoing transaction?  ?? So what my wallet says and what blockchain.info says do not measure up. I sent 18.1, but it seems somehow blockchain is saying i only sent 14.2, then it added the 3.81 i was supposed to get through sendshared, yet the full 18.1BTC is gone from my wallet!! Basically i am out that 3.81BTC, and would really like to know where the hell it has gone. Any suggestions, have contacted customer support with blockchain.info but no reply in the last 48hrs. |

In order for bitcoin to grow, we all need to be spending lots of them on actual products, not just hoarding/trading. Here in Australia buying a laptop can be expensive we pay up to double our US cousins some times....last lenovo i bought i had to set up mail forwarding, which is a pain and means shipping takes forever...now with BTC i would like to buy online for US pricing and have one shipped straight here.....anybody know any reliable, trustworthy PC vendors with worldwide shipping......or have i uncovered an arbitrage opportunity  ? |

Hey have used send shared a few times with no problems, for under 10BTC it is usually pretty fast, but the last time i sent in around 4BTC and 12 hours later it still has not arrived. Anybody else had any experience with wait times this long?
