if coins have enough priority and amount > 0.01 btc then you can send money without fees. Actually it's a cool idea. 90% of my transaction I sent without fee. The average confirmation time ~ 50 minutes. More info: https://en.bitcoin.it/wiki/Transaction_feesDitto. Priority and size matter. Most wallets will calculate what fees, if any, are needed. Usually it is best to rely on those calculations. |

Can't tell if this is serious or not, but CPU mining has been dead for years particularly on a phone. GPU mining is pretty much dead and has been for more than a year. Your phone is contributing so little there is nothing to report, sorry to say.  |

One thing to also check is to ensure "app nap" is off. That shouldn't cause a crash though.
Did you try running disk util to repair disk and permissions? (Make sure you have many backups of wallet.dat) This could be caused by something unrelated to bitcoin.

Even if the download speed is the bottleneck, it still seems like sharing all the information across the network will eventually be too slow. And I know that a block can contain more transactions than others and that the difficulty changes every 2016 blocks, but more transactions means more data to transfer. That's why I did all my calculations in terms of # of transactions per seconds, not blocks per second.
I'm not sure what you are implying by the bolded part with regard to your computer being able to keep up. |

If flood is a problem, lock and unlock can be charged as any other transaction.
Just go ahead and implement it and do a pull request. That will give everyone time to evaluate the proposal in reality and determine whether this hard fork is justified. |

I'm fond of things that liberate people, rather. And I sense something quite liberating about this kind of lottery. You would be able to play an hazardous game without a sense of loss.
I too am fond of things that liberate people. As an aside, if things can be implemented without a hard fork for bitcoin, that is a good thing because then it is a much more difficult target to attack. If the bitcoin protocol and software itself implemented any type of gambling, it makes it a bigger target. If they can be implemented on top of the blockchain, bitcoin is less of a target itself and you get the benefits you may have been thinking about regarding another use for bitcoin. :-) |

This just isn't the purpose of Bitcoin. Gambling can be implemented outside of the network, but a built-in lottery system would only add strain with no real benefit.
Add strain to what - Bitcoin network? Don't we want more transactions with fees, not less? And it can't be implemented outside the network, since sending to unspendable addy would reduce the number of bitcoins significantly if it catches up and many people start to play, the only way to recover those burnt coins is through alternative coinbase. It can be implemented outside the network, just not using a burn address like this. And what do you suggest using instead of burn address with keeping it 0 trust? Something like what is discussed here: https://en.bitcoin.it/wiki/Contracts#Example_8:_Multi-party_decentralised_lotteriesand http://eprint.iacr.org/2013/784e.g. As an instantiation of this idea we construct protocols for secure multiparty lotteries using the Bitcoin currency, without relying on a trusted authority. By “lottery” we mean a protocol in which a group of parties initially invests some money, and at the end one of them, chosen randomly, gets all the invested money (called the pot). Our protocols can work in purely peer-to-peer environment, and can be executed between players that are anonymous and do not trust each other. Our constructions come with a very strong security guarantee: no matter how the dishonest parties behave, the honest parties will never get cheated. More precisely, each honest party can be sure that, once the game starts, it will always terminate and will be fair.

What do you mean with the bootstrap torrent? How can I use it?
...
bootstrap.dat is just a download that gets you pretty far along in the sync. By the way, make sure that you have "app nap" turned OFF for bitcoin on Mac OS X. In the Finder use "Get Info" and make sure that "Prevent App Nap" is checked. Anyway, a location for the torrent is here: https://bitcoin.org/en/downloadSome discussion here: https://bitcointalk.org/index.php?topic=447749.0and here: http://bitcoin.stackexchange.com/questions/20847/how-to-use-the-bootstrap-dat-in-mavericksThe wallet directory/data directory is here: "/Users/<your-user-name>/Library/Application Support/Bitcoin" which is the same as: "~/Library/Application Support/Bitcoin/" You can put the torrent in there. You should ALSO make a backup of your wallet if you don't already have several. Just to be safe when screwing around in there. Hopefully that helps a bit. |

The difficulty is now too high for investments in mining to really be profitable unless you do it really big... which most people cannot afford to do..
Honestly I can make 100 or 200 per day selling BTC on localbitcoins.com, which I think is a lot more profitable and less risky than mining.
Do you buy from exchanges and sell locally? Coinbase and sell locally/online. I would actually make a lot more $ if I didn't have to wait 4 damn business days between purchases. It is possible to wire $ to an exchange but you still have to wait 2-3 days for the wire to go through and it is possible the price could rise before then, causing a loss on the trade. Where are you located? I would be surprise if you can keep doing it for long if you are located in US or Europe before authority knocking on your door. Why would they do that? It's not illegal to trade bitcoins. Unlicensed money transmitting is what was being referred to, I believe. |

Makes sense. I think wealth preservation and speculation are also valuable uses for bitcoin though. In short, bitcoin's uses are not just a binary proposition and includes speculation. Just like other currencies hedging currency risk is a valuable use. Perhaps a better way to think about it is that speculative uses were dominating use for a while at the end of 2013 whereas things are now shifting to a more balanced use model. :-)
You are right about the value, reminds me of some people: they know the price of everything and the value of nothing.

Protecting from host, protecting from users, protecting from outside attackers are all considerations. It isn't something to take lightly, cold storage is a consideration for a majority of the coins. VPS can be a problem too. One host wasn't erasing the disk space between VPS sessions for example. You have to worry about hypervisor issues etc. A lot also depends on what attacks you are trying to prevent. E.g. if this is on a coin with a total market cap of $1.00 then it really doesn't matter much. Here are a few more threads, there have been a number of discussions which should help to start. Experience will be key though: https://bitcointalk.org/index.php?topic=106339.0https://bitcointalk.org/index.php?topic=27250.0 |

the amount of fud about bitcoin is much big... was there similar fud about internet in its origin years
Yes. "It is only for porn." "No one will put their credit cards online, it isn't safe." "It is too hard to use." "Email is to ephemeral, I like hand written letters." "Email gets lost." "Web sites are scammy." "Banks can't be online without being hacked." "It is a fad." And then there is an old favorite from the 'genius' Paul Krugman: "By 2005 or so, it will become clear that the Internet's impact on the economy has been no greater than the fax machine's."
etc. Every change is met with FUD from entrenched interests. (They just didn't always call it FUD!) |

Do you need to quote the second item if you are running this from the shell? Not by the computer to try it. e.g. a ' before the {  ? like: bitcoind sendmany "" '{"mvTt8hav6e9ESjSrXJ1yaJhyULHv8ywcN7":50}' 1 "To the Faucet" bitcoind sendmany "SomeAccount" '{"myeTWjh876opYp6R5VRj8rzkLFPE4dP3Uw":10,"mikZVLuasDcY1Jmph3rqgT1NXfjB1srSEc":15,"mvTt8hav6e9ESjSrXJ1yaJhyULHv8ywcN7":50}' See: https://bitcointalk.org/index.php?topic=4254.0 |

I have a bunch of unconfirmed transactions (not even 1 confirmation) over the last 3-4 hours.
what's going on?
Do you have the transaction numbers? Definitely check somewhere else than blockchain.info. |

...Bitcoin is not to compete with fiat, but to compliment it.
Why bitcoin, you look wonderful today. Have you lost weight? You look 10 years younger!  |

I feel Bitcoins are experiencing their low ebb and the lowest one has not come. However, it is not risky for newbuyers to store some in the low ebb for long-term consideration. Besides, many hoarders would not give up Bitcoins for they are hot for the great technology and the fans of Satoshi Nakamoto, so does Litecoin.
Lowest ebb? No. In December of 2011 BitStamp reached a lowest ebb of approximately $3 +1 And there were the same messages when it hit dollar parity for the first time. Slashdot was full of FUD then. ;-) Plus the "It is a ponzi," "It will crash from here" and "It has no value and will got to zero" talk. Until there is a lot more usage there will be volatility and even then there will be some. The next halving and more usage are (as previously) important. So, don't panic. ;-) |
