i find both parts of this story depressing.
My view on it. |

You don't seem awfully surprised your kernels were leaked. Or are these separate work?

Right now your safest bet is to use the hardware wallet Trezor.

Lets summarize or TLDR; - Bitcoins don't actually exist.
- Wallets store one or more private keys.
- A private key is a very large integer(number). Link to infograph https://i.imgur.com/IL6PV5E.jpg
- Any type of bitcoin malware that has access to a machine where an unencrypted wallet resides CAN steal the bitcoins.
Your description is correct and helpful but your first point "Bitcoins don't actually exist" in wrong. Of course you can discuss the ontology of what it means to exist but in the common meaning of the term bitcoins do exist. Bitcoins are possession of the private keys which are necessary to move bitcoin outputs in the bitcoin network. You + the private key + the bitcoin network are the bitcoin. All three exist. It is in the network that they exist. By participating in the network you are accepting the promise that the bitcoins are recorded there. It is in the private key that they exist because that is needed to move them in the network. But the ultimate place they exist is in you, in your acceptance that the network will allow you to transfer them to another address and that such transfer can be exchanged for goods or services. In this sense they exist just like dollars exist. You need the network (The United States), the right to transfer (bank account, cash, your signature, other recognized means of ownership) and the expectation of value (you expect that dollars can be exchanged for goods and services.) My TLDR was a summary of what was discussed here. First post https://bitcointalk.org/index.php?topic=892752.msg9832308#msg9832308However even the Core developers have stated that same thing. |

The link is very interesting, can I ask a few questions? 1- What does it mean to "f*ck up with the R values"? 2- Why does the impossibility of a computer counting to 2^256 prevent it from attacking bitcoin? 3- And why doesn´t that prevent the computer from generating private keys and making transactions? 4- Which makes me wonder, if private keys are generated randomly, then is there a chance of the same private key being generated twice? 1. R value is part of the algorithm by which a transaction is signed. If the same value is re-used twice, recovery of the private key is trivial. This only happens with badly written code/programmer errors. 2. Since a computer cannot count to 256 in a timely manner(billions of years even if a super computer was used), it cannot check EVERY private key for a balance. 3. Because there are so many. There are as many private keys as there are atoms in the UNIVERSE(well, slightly less than that in cosmic terms). 4. Nothing prevents it, but so long as entropy is sufficient(these are random bytes generated by your hardware) this is extremely unlikely. Or as somebody said, it's infinitely more likely to get hit by lightning 7 times in a row while winning the lottery 7 times in a row. 1- How can I be sure I will never "f*ck up my R values"? 2- So, there are exactly 2^256 private keys total? 3- And from what you said, I suppose it´s not profitable to get your computers to check one by one for balance, because there are so many and they will probably never find one that has already been used? 4- How many digits has the number 2^256? 1. You can't. It all depends on the programmer. 2. No, slightly less than that. Moreso, because of a different part of the address generation algorithm, there are actually 2^160(still a very large number) possible addresses from the ~2^256 private keys. 3. Nope. 4. 115,792,089,237,316,195,423,570,985,008,687,907,853,269,984,665,640,564,039,457, 584,007,913,129,639,9365. Don't be confused about the small appearance of this number. I assure you, it's incomprehensibly huge. Most people know how to "count" only to the bolded part. A quantum computer built using quantum entanglement(one has not been built that uses this only one with quantum annealing which is not the same) can pose a threat to all crypto. But orders of magnitudes more qubits than the D-Wave one. The other method is to build the best possible computer, quantum or not with 100% efficiency, use a dyson sphere to trap a young star and travel through a wormhole that connects billions of years in the future to obtain the results. |

Sounds like a problem with your browser's or blockchain.info's code.

Also Ukraine has banned fiat or so I read and China has said that private currency can co-exist with govermment issued currency. MS also accepts Bitcoin(indirectly). Either way, all positive news lately, there was just bound to be some rise.

I've always wondered what is a 50 or 51% attack?
The gist of it is that if someone has too many miners, he can chargeback(reverse) his own transactions, plus other unsuspecting people's transactions too. Only if he's a bad guy/woman though  |

I understand the concept of public-key cryptography, but not the math behind it.

Hey if you have nothing to hide, you don't worry. However, Its annoying to know that someone snoops around your dirty underwear. If users are careful, though, the probability of getting caught is minimal.
This is a bad attitude to have. People deserve privacy. Exactly. Who or what gives them right to poke around my darkest secrets? I want that person/thing to give me the same right to poke around theirs too. I don't think anyone should have the right to invade others' privacy without their permission. might be worth trying gchq spy on me ill go for a walk around the HQ... its only fair  Hahaha. >>Guy goes to the bathroom. >>NSA enters too. >>NSA peeks over the stall and asks guy what he is doing. >>Guy responds. >>NSA asks "Can I watch?" >>NSA doesn't particularly care about the answer. |

Haven't you heard? Fungal Meningitis is responsible for a dozen of terrorist attacks, money laundering operations, human trafficking, crimes against humanity.

So my interpretation of the TPB response is, they are taking this opportunity to re-evaluate their life priorities and probably call it quits.

I think Satoshi has succeeded. Succeeded in showing us that it's possible to stay anonymous in this day and age. He also showed us what would happen if his identity was exposed, like the Dorian Nakamoto ordeal.

That's the other thing about reddit, it has sections for nearly any type of hobby or thing you might be interested in. Like seriously anything.

Hey, I didn't either. I only started using it this summer and since then it has become a daily routine to check what is up.

Participate in the auction number and not as good as last time funds.
Price went down, many people probably lost money from the previous purchase. |
