Wikipedia's current bitcoin entry is not reflective of even a significant subset of factual information, and has been the object of several editwars and obvious and deliberate censorship events. Treat the information there as suspect. | 0 | midnightmagic | 2015-06-08|12:51:25|UTC |

As opposed to Wikipedia, the Bitcoin Wiki, here: https://en.bitcoin.it/wiki/Main_Page has between the masses of spam and commercial fail-edits, significant, and highly accurate, curated technical information about Bitcoin. | 1 | midnightmagic | 2015-06-08|13:14:16|UTC |

The UPnP library included in Bitcoin Core <=0.11.0 has a (LAN) vulnerability at startup, fixed in 0.11.1 and 0.10.3. You must upgrade. If you can't upgrade immediately, you must at least disable UPnP before you next (re)start your node, via any of: GUI: Options > Network > Map port using UPNP (uncheck); bitcoin.conf: upnp=0; command line: -noupnp. | 17 | iwilcox | 2015-10-09|16:24:25|UTC |

Transactions have no from address; while they have some last-sent-to addresses, trying sending coins there can result in a variety of problems including coin loss. See https://en.bitcoin.it/wiki/From_address | 5 | iwilcox | 2014-10-26|03:36:17|UTC |

Samourai, described as a privacy-enhancing wallet and, peculiarly, rated by a well-referenced but terrible study as more private than Bitcoin Core, *still* reports back entire groupings of addresses to blockchain.i* and has *poor* and *identifiably different* tx building logic. Its github repository is merely a code dump; if you value your privacy, DO NOT USE IT. | 1 | midnightmagic | 2016-04-27|04:11:39|UTC |

Pre-ordering mining equipment is very high-risk. ASICs are often overpromised & underdelivered, some never arriving or arriving very late/below spec. Even if they arrive on time, difficulty rises often exceed predictions and few models reach profitability. | 30 | iwilcox | 2014-03-19|13:14:57|UTC |

It is risky to post addresses that you use or know of. People are combing these IRC channels to perform correlative attacks on innocent users. It also hurts the privacy of the people you deal with. If you don't want to see this message, please add the keyword validateaddress anywhere to your line and the bot won't trigger this warning. | 1 | midnightmagic | 2017-11-17|18:40:17|UTC |

Many popular forms of payment, such as PayPal and credit cards, allow the sender to claw back the money via a 'chargeback'. This is very undesirable for the seller of bitcoins, so you'll often have trouble convincing people to trade on these. See https://en.bitcoin.it/wiki/Payment_methods for comparison of payment methods. | 40 | iwilcox | 2014-03-16|00:48:51|UTC |

Bitcoin Core is affected by OpenSSL heartbleed in two narrow ways: if RPC over SSL was on and exposed to the public, or if the payment protocol was used with unknown sites. Fix is in v0.9.1! https://bitcoin.org/heartbleed http://goo.gl/5nRAB7 | 30 | midnightmagic | 2014-04-11|17:13:39|UTC |
| 18 | Productive mining is a specialist industry now, requiring ASICs. On CPUs, GPUs or FPGAs you'll pay more for the electricity than you'll make back in Bitcoin, even on free hardware. Even on ASICs you should treat mining as an educational hobby with a net loss. See also !preorder. | 111 | iwilcox | 2014-03-19|13:15:16|UTC | |
| 19 | The old Bitcoin faucets were a way to bootstrap the currency. These days they are almost entirely pointless scamsites that farm you for views for less value even than the old pre-$1 faucets would hand out. Except for testnet faucets, don't waste your time. | 1 | midnightmagic | 2016-04-04|17:43:56|UTC | |

An Android vulnerability dubbed 'Fake ID' has been found which allows malicious apps to access wallet app data. We recommend installing only Play Store apps (which get scanned for malware) at least until your phone is patched.

Child Pays For Parent. A miner supporting CPFP will consider a chain of transactions that depend on a parent, rather than just the parent, when picking transactions to include. The typical example is a parent with no fees but with children paying enough fees to cross some fee threshold. A node might also use CPFP in relaying decisions. | 4 | iwilcox | 2014-03-19|11:37:48|UTC |

If you have your IRC client force SASL authentication with Freenode, and disconnect immediately if SASL authentication fails, you will almost never have to be on the network without your GECOS cloak. | 0 | midnightmagic | 2015-11-14|23:47:21|UTC |

#bitcoin topics are not universal. We have a topic, and we have rules. They are a strict superset of Freenode's rules. That means Freenode + Us = restrictions. This is not free speech being trampled on: you only get to say that if we arrest you and throw you in prison. https://en.bitcoin.it/wiki/Bitcoin_IRC_Channel_Guidelines http://xkcd.com/1357/ | 2 | midnightmagic | 2015-06-11|07:09:22|UTC |

The biggest exchange can fail with near-total loss of funds (e.g. MtGox.) Don't leave money in exchanges you're afraid to lose; you are merely an unsecured creditor if they go under; exchanges can freeze your accounts or arbitrarily prevent withdrawals; until you cash out, all you are buying is a PHP variable; AML/KYC mean exchanges can easily steal your identity. | 5 | midnightmagic | 2015-11-15|00:00:16|UTC |

The 'random' button on brainwallet.org appears to create maliciously weak private keys which can be broken by a third party. Using the HTML source offline does not absolve this vulnerability. Any funds stored in these addresses have been stolen, or are at immediate risk of being stolen. | 17 | nanotube | 2014-06-27|03:26:08|UTC |

The Bitcoin blockchain is the data structure that bitcoin software uses to build global consensus. Blockchain.info is a web wallet company with an unfortunate history of breaks and significant, bitcoin-losing security problems. b.i is NOT a component of Bitcoin, but rather a company that just decided to use the blockchain moniker.

OpenBazaar began as a strongly privacy-enhancing market by among others, Amir Taaki, but since it was forked into OB has dropped most of its privacy-respecting goals. Its new devs claim the use of a Tor HS for OB requires NAT traversal (not!) and that no ideal survives implementation. They also claim Tor is a bad platform for OB's chatty p2p. Use cautiously. | 1 | midnightmagic | 2016-04-27|04:21:21|UTC |
