first of all, whats the poll for, it doesnt give any information. secondly i would choose blockchain.info, as you dont have to keep anything on your pc with it and everything is on the internet
While Blockchain.info is currently the only online wallet that lets you have control of your own private keys, they have had a few incidents in the past where users either lost coins or came very close to losing coins. Their most recent incident happened just over a week ago which affected a subset of users of their Android app who were running older versions of Android and perhaps more importantly, exposed some pretty sloppy coding practices on their part: http://bitcointalk.org/index.php?topic=1085983I'd probably still consider them to be better than your typical online wallet based on the fact that you'd still have access to your coins even if they were to suddenly shut down but after seeing what happened recently, I'd be wary of keeping anything more than a couple of BTC in there. I would say greenaddress.it would be a much secure choice. Considering that blockchain.info identifier is also quite long, you can switch to greenaddress.it and use their memoric. They also create 2of2 multi sig addresses and allows you to set a limit. They will send a nlocktime file for you to redeem your transaction when it expires. It is quite secure too. |

Thank you for all the replies. It is a lot for me to soak in.
I am very new - I did get electrum and multibit working on my RasPi2. However never got MBHD to connect to server as easy that electrum did.
still trying to compile bitcoin core... this time I used the incompatible database option and we will see if it works.
There is a lot for me to learn.
I agree a local wallet is more secure. However that I have cloud-based options are nice.
thanks again
Anything hosted in the cloud isn't safe. Desktop clients is much better.
I also choose electrum, keep in mind downloading the bitcoin blockchain could take a bit and lots of space, well some people feel safer doing it i dont blame them, but i havent had any issue with electrum since I started using it.
Electrum is a SPV client which is generally quite secure but it must trust the miner to follow the rules and it doesn't offer as much anonymity and features and Bitcoin Core. You can easily attach a HDD to your computer or raspberry pi. Cheapest at my place starts at $50 for 1TB. Electrum is still okay for normal joe who don't need much anonymity. |

true, and all of these risks can be minimized with transparency; if the site shows their bankroll at all times as well as proof of funds, investors can see for themselves weather or not the site's investment system is legitimate or not. i believe the lack of this transparency was why dadice decided to halt their investment option as well
Dicebitco.in offered exactly that but it still ended up making its investors lose money. It offered proof of funds and the size of the bankroll was always shown on the upper left corner of the site: Just passed 1k+ Bets in less than 3h O_o  Quote from an article on the site's demise: Since the beginning of the authorship of this article, DiceBitco.in owners manl and gerry have stopped responding to users on Bitcointalk and a player, going by the name mateo, has continually placed bets with a near perfect win ratio, emptying the site and stealing the entireity of investor funds. Link: http://cointelegraph.com/news/112470/dicebitcoin-accused-of-cheating-playersMany others fell from the same thing. Even TF's sites got raped. The only truly safe place for your money is in your own hands. Coinbase offers insurance, but if you read what they say, if their service was hacked or someone found a way to exploit addresses to wipe them out, insurance would not cover the situation. The interesting part is that doolgus trusted it and everyone just followed him. Investing in a gambling site may not be the best way to earn a profit. The owner can see the seeds and predict the rolls hence cheating investors. This is the main reason why primedice don't have a investor option. Security wise, the cold storage is intended to be secure. If one properly generated a cold storage address, the probability of it getting hacked is very low. In TF's accident, the majority of coins wasn't kept in cold storage which would be much much more secure. |

everybody told me that mining is unprofit,so all i have to do just looking for a better way to get bitcoin
mining is not profitable these days because bitcoin price is very low unlike in 2013 to early 2014 where bitcoin price is at its peek. They weren't much more profitable at that time either. The difficulty was rising tremendously. Even if you chose to buy at the $300-400 price point, by the time your ASIC comes, you won't have much time left to mine. Furthermore, the price crashed a lot in the coming months and people were losing lots of money. If you brought at the $400 price point, you could have just sold it when it reached $1000. Buying Bitcoins is still the most effective way to earn. |

Be careful, I have heard stories form people who burn out their computer from mining too much. I don't think that computers, or at least the consumer computers, were really meant to be run at 100% processor for 24/7. You can look into minergate, they let you choose how much cpu power to mine with. I only tried it briefly so I can't say if it makes money, but you might have fun with it. You might also want to look at grid coin, a really interesting way to mine and contribute at the same time.
this could happen with a laptop or netbook, because they have a bad air flow, and when the dust accumulate their fan practically stop working, still the cpu will turn off automatically, so the damage will be done to the motherboard or the integrated vga, in most cases Laptop or netbook typically have lower TDP and would automatically throttle back when the temperature is too high, if I'm not wrong. This could happen with a desktop computer too. Some desktop computer would have very bad cooling aka. intel stock cooler. Buying any type of miner and attempting to mine on your own will prob be unprofitable. If anything, take a look at some Cloud Mining Sites, yea they have fees, but the fees end up being cheaper than the power costs you would pay long term.
That's not fully correct in all the cases. Cloudmining are mostly scam. They include management fees which is included in the fees they would charge. It isn't recommended to cloudmine as you have more risk of losing money with an anonymous company than buying a miner from someone in the forum or reputable manufacturers. |

What material they use to make those Black-Boxes inside an Aeroplane, that thing can take a good beating and it seem to survive in heat, water, etc. It'd be pretty safe to put some keys inside a safe box made of the same material.
But the thing is none of these things are safe from physical theft, they may last for life long but if a thief is able to get to them, they will be able to swipe off the key and steal the funds, they don't even need to move the carved stone or whatever and when and if bitcoin gets more mainstream we will see more robberies to steal people's stacked bitcoins.
BIP38 encryption? IMO, they are pretty secure from bruteforcing if you choose a hard password. Of course, this wouldn't be viable if you do lose your password but you can still store the password somewhere safe, far away from your paper wallet. Alternatively, multi sigs can potentially prevent this problem by either placing them at a few secure locations or with a few of your trusted friends. If you need to spend it, you would at least need m of n of the signatures. This would protect against theft and it would provide redundancy. |

I would suggest investing them in a trusted gambling site, I always give this advise because if the website is legit. You will most likely make a profit  you cant trust any of the gambling websites as they easily might turn to scam i think the best would be to save bitcoin you get and wait for price jump there are plenty of trusted gambling sites run by trusted people who have been on this forum for quite a while; primedice and 777coin are just two that come to mind. no need to go around spreading nonsense. Neither Primedice nor 777coin have investment option. What he said was true, lots of gambling site accepting Bitcoin isn't trusted enough. The one that was the most trusted was just-dice but they moved it to clamcoins. Even though you can still invest there by buying clam coins, the risk of the clam coin market is too high. |

its better to just do one 90% roll on primedice and then walk away.
if you really do want to invest people just hold it, and add it up to .1 btc eventually.
It's actually quite risky. People have lost a thousand BTC for rolling at 98%. The risk is lower with 90% but it is still there. There is still a good chance that you may lose it on the first roll. Furthermore, you will only earn 0.002BTC. It isn't worth it if you have a huge possibility of losing on your first bet. |

by posting and investing bitcoin..!!!
Would you mind to share where do you invest your bitcoins? The safest way to earn bitcoin with trading is through arbitrage. In short, this means that you see an opportunity to buy an asset in one place for a certain price and sell it immediately at another place for a higher price. It is important that you know you can sell the asset immediately at a certain price. If this does not hold, then we are talking of speculation - and it is closer to gambling imo. Not realistic with Bitcoin. Since cryptocoins is highly volatile, the short time getting it to confirm can mean a huge fluctuation in price. Most exchanges would require a 3-6 confirmations for solely Bitcoin which makes this highly risky. If people choose not to buy at the price you listed, you would make a loss. The exchange fee can minus a large portion of your arbitrage profit. Or enter a captcha in every faucets you can earn from it but don't hope that you can earn a big coins, but some people here in my country, they have a site that even they are offline they can earn from a faucets, and they using vpn so that they can hide their IP address. Tell me that site. I believe if images are preloaded, it would be easy to bot it. VPNs are mostly blocked around faucets due to abuse and most sites only allow the address to have one claim per specified period. |

Their main line of attack against Bitcoin is their undeniable superiority of volume of transactions per second. In the latest Gavin's approach which is 8mb increase every two years, we would have the following:
(B=bytes, b=bits, 500 bytes/Tx)
2016 8MB 0.1Mb/s 26Tx/s
2018 16MB 0.2Mb/s 53Tx/s
2020 32MB 0.4Mb/s 106Tx/s
2022 64MB 0.9Mb/s 213Tx/s
2024 128MB 1.7Mb/s 426Tx/s
2026 256MB 3.4Mb/s 853Tx/s
2028 512MB 6.8Mb/s 1700Tx/s
2030 1024MB 14Mb/s 3400Tx/s
2032 2048MB 27Mb/s 6800Tx/s
2034 4096MB 55Mb/s 13600Tx/s
2036 8192MB 109Mb/s 27300Tx/s
END OF BLOCK SIZE INCREASE
That would mean it will take 20 years to reach Visa's transaction peak volume. Even with LN, we'll still have problem to reach the ultimate goal, which is worldwide fluid usage. Im just hoping solutions are found along the way.
It is our current solution and it was introduced to please the masses. I think that bitcoin for not all that much popular to justify further and faster block size increase. In fact we don't need TX number increase, because there is not need for it. Of course Visa or Mastercard can process more transactions, because they are top dog companies with millions of clients. Bitcoin is not that big, not yet. So their argument is invalid in my eyes. Blocks are starting to get full. If the increment of block size has to be made, it would be great to increase it slowly rather than increasing it all at one go. Also, the increment of block size can help to reduce the impact of potential attacks against the network like what is happening right now. The blocks can handle only around 1000 transaction [If pools set it at 1mb max limit and each transaction has 1kb of data]. Medium scale attacks would be very effective in attacks to increase the time other transaction take to gain a confirmation. Increasing the block limit may not solve it but it will at least help to reduce the impact. |

I have a computer which will not used, however, it is about 4-5 years old already, is it worth to use it to mine BTC? If yes, how much will I expect to get in 1 month  I suggest you to forget about mining. Sell your computer and buy bitcoins, after that you can buy high rank forum account and join signature campaigns so you can earn more. Also a good idea... just wondering how much will an acc cost... Jr. Member/newbie =0.02-0.04btc with potential FM member = 0.02-0.04btc Fullmember = 0.05-0.1btc Sr.member = 0.2-0.3btc Hero 0.4-0.6btc Legendary 1-2btc wow...1-2 btc for a Legendary acc how long time will it take to become Legendary? coz i really can't understand the calculation of activity Legendary is currently between 775 and 1030 activity. If one stays active and never misses a activity, it would be 27 months. If one is unlucky, it would be 36 months. It is currently very rare and the price is because of the rank and nothing else. Others are priced mostly based on number of open campaigns. The amount can vary depending on trust, age and post quality. |

Anyway OP, if you're still interested in mining with your computer then you could try mining altcoins and converting these to bitcoins using an altcoin exchange like Cryptsy. There are many altcoins out there which can still be mined using CPUs or GPUs. The only ones which have ASICs built for them are SHA-256 based coins like Bitcoin and Peercoin, and scrypt-based coins like Litecoin and Dogecoin.
Agree. In most country, the electricity cost will never make you profit mining Bitcoin. However, mining altcoin might give you a little profit. Well, most altcoin difficulty is lower compared to Bitcoin. Also, instead of mining by yourself, joining a pool might speed it up. If you intend to mine Altcoin and join a pool.. Choose a pool which will automatically mine profitable altcoin and exchange it into Bitcoin for you. The reason for the lower difficulty is also the lower price and the lower profitability. If the coin is profitable, ASIC miners would be rushing to mine it for sha256 and scrypt. The main problem with multipool is that they may only exchange your coin at x time per day and if the coin crashes before the time reaches, you're doomed. |

I would like to ask the legality of this ;
If I own a website and through that website , I use every visitors computer while they are visiting (not after not before , no virus just WHILE they are visiting) to mine certain CPU coins (well it would be great if I can find a multipool to mine the most profitable CPU coin) would it be illegal in anyway?
This will not be against their will of course , think of a game , the more you stay on that page and let me mine coins with your computer , the higher game currency you will get to play the game. That way when you are away , you open that page and let me mine and when you comeback you can play the game and be better then when you were last playing. Kinda like fremium offer with many mobile game apps.
edit : also do you think this would make any coin at all? depending on how many users of course but for example how much do you think 50 people at a time would make everyday?
Letting them know about how much of the resources will be used and asking them to agree to the agreement could minimize any implications. If I'm not wrong, you have to design the entire thing yourself. I don't know of any premade webpage CPU miners for all the algorithms available. It can surely make some money but don't expect it to be very high. Altcoins are highly volatile and the hashrate depends on how good you optimize the scripts. |

I have a computer which will not used, however, it is about 4-5 years old already, is it worth to use it to mine BTC? If yes, how much will I expect to get in 1 month NO you can make your computer dead With good cooling, no but degradation is possible with 24 hours full load. Mining with old computers is no longer a good choice. You can still hook up a USB miner or any other miner to mine but I doubt it would be profitable unless you have no electrical costs. You can also buy a raspberry pi to hook it up. Most signature campaigns do not accept low quality accounts which many people are selling right now. I would suggest that you could buy one from a trusted seller with assurance that the post history is good. |

i would suggest to lend them with 50% interest, use escrow for this, i think that lending is the best way to increase your bitcoin balance, with a very minimum risk, because you can use a trusted escrow or ask for collateral
If you are looking to lend out 0.02BTC at a high interest, you won't be making much profit or will have very less people looking for a loan from you. The current lending section has various lenders offering no collateral, no interest loans or at least with low interest. Escrows doesn't really help if you're lending without collateral. Lending 0.02BTC secured with collateral isn't that realistic since its quite a low amount. You would either get a lot of newbies trying to get a loan from you or have no one. Gambling site isn't much of a better investment place than lending. Whales often wipe bankrolls and the owners may not be trustworthy enough and they hold your coins. In the long run, you will only be earning the house edge minusing the commission taken. It may not be profitable. The best IMO would be investing in an high quality account and joining signature campaign. |

Hello,
I have a question about mining on dedicated server. I have the following hardware:
2 x Intel Xeon E5 2660v3
256 GB RAM
3 x 500 GB SSD
1gbit dedicated network
Now how much would i expect to make per day mining litecoin or bitcoin? About profitable dont mind this as i pay completely 0 for the server and i have like 40 of them online doing nothing.
Processing speed is all that matters, ram, storage space/speed, network speed doesn't matter. It is slightly profitable but you can generate more website by renting it out or hosting a website. For all of the coins, CPU mining isn't viable anymore. Bitcoin and litecoin is dominated by ASICs and other coins are dominated by old GPU miners. Dedicated servers don't have that good cooling and you may end up killing it instead of generating a positive return. |

Only legit cloudmining I know is cex.io.. but fees are just too high so it's not worth it :/ Maybe stay away from cloudmining, you will probably get scammed :/
Cex.io have suspended cloudmining operations a few months ago or so allegedly because of low bitcoin price. But surely they are not more legit than Hashnest which belongs to the main manufacturer of asics. I agree with you Cex.io is 1 of trusted company where we can get full acces in cloudmining but Profit is very hard in cex.io we need more than 1 year to ROI I do not think you have been paying attention. Cex.io have not enabled cloudmining since January, as it is unprofitable. This information is stated in several places on their website. Since they doesn't seem to be a ponzi, I think they are mining for themselves with the equipment their customers bought them. Everybody knows bitcoin mining is still profitable and a lot of companies/individuals still mine. A company this big should be able to cut fees if necessary and if circumstances demand it. The problem is that they don't want to. AMHash also didn't seem like a ponzi at first but look at them now. Truth is, they didn't have any customers sending them equipment and they would be all over the news if they decide to stop cloudmining but not returning their equipment. The decrease in pricing has made it unprofitable to even cloudmine. Cex.io aren't using the most efficient hardware and they can consume lots more electricity. They probably needed a dedicated datacentre for those equipment and they probably need to pay rent too. Don't forget onsite security and technicians. If they can still cut the maintenance fees without going into a loss, they wouldn't have shut down. |

This is totally ridiculous. Why should the United States government mine bitcoins? I can't even find a single reason.
To have more control over Bitcoin when it gets big of course. You aren't a big thinker arent you. They can't control Bitcoin unless they gain significant portion of the hashrate. The only few attacks I an think of is the 51% attack which requires 51% of the hashrate to 100% succeed. Impossible since half of the network hashrate is already 170PH. They can blacklist addresses and exclude them but they have to get at least 50% to slow them down significantly given that on average, they have a chance of finding 1 block per 2 blocks mined unless majority of the network collaborate which is impossible. |

Litecoin was supposedly GPU resistant. Got broken. ASIC resistant? Got broken again.
The main reason why it is considered better is because the confirmation time which is 2.5minutes and possibly the increased cap on coins. I don't see it as being better though. Faster confirmation means more orphans and lesser security compared to Bitcoin's one confirmation.
