There is no "admin". Is a decentralized currency, meaning that anyone who installs the Bitcoin wallet locally is a station on the general network and holds a complete copy of all currency transactions. When someone buys or sells , The transaction is registered and immediately copied across the network to all the software holders. There are no central servers, so it is not possible to drop or close the stand on the currency and / or its users.

By the way, what it means is that if you want to install , Make sure that you have at least 15-20 GB available on your hard drive, because this is the amount of information that you download during the next few days to your computer before you can see changes in your Bitcoin balance. , But you will not see it updated in your local wallet until the entire BLOCKCHAIN ​​is down).

All this by the way is not valid if you open a wallet on the ONLINE service, because then they hold one copy of the BLOCKCHAIN ​​for all the wallets in their service.

Is there a more efficient miner for NVIDIA cards? Because I understood that, Mostly older cards get a much higher output of Mhash / s I miner on 120-130 environments with GTX680 on mild OC.

Meanwhile I have 0.07 mining, I am waiting for the fall of the currency and then I will buy some units, I hope he will fall (because when he falls he usually rises, and sharply)

One of the most effective Bitcoin addicts is CGMINER, But do not ask me how to set it up and work with it. I work with GUIMINER, That is one of the simplest and most flexible. It also opens an opening to work with several miners simultaneously or separately.

Beyond that, They are not the most efficient cards for Bitcoin mining. In fact, they are a bad investment in that direction. They're great for games, but their architecture does not work well when it comes to parallel tasks. Now someone might jump and say it's not true, but the facts do not lie-and you'll need a much more expensive card To reach the same speed as Bitcoin's bitrate calculation than AMD / ATI.

I work with ATI 5850 - one of the most effective cards (in the context of cost / benefit - the speed of this card is about 270) for Bitcoin mining. Incidentally, this model is no longer manufactured, nor is it easy to find used ones - precisely because they are so effective. But in general, tickets from the series , Combined with the right drivers, will give good value to mining. Today, mainly due to the introduction of dedicated computers into the business, it is much less profitable to enter the mining.

So I understand that computers with a built-in video card are not really relevant?

I have dozens of computers that 90% of the time in IDLE but most of them are DUAL- And wondered if it was possible to take advantage of their spare time ...

Just to get an idea - how many "miner" such HD5850 a day?

They are relevant, but they will only be mined using the main processor. And it will be very slow. You'll need hundreds of them to get to the pace of one dedicated video card.

Anyone who wrote the software can cheat. He could add a sea of ​​money to his wallet.

This claim has been raised many times in the past. The point is, the founders did not have to cheat at all. At first there was no value for Bitcoin, and the mining was so fast and easy that within three days you could cut a block of fifty coins. So it's possible that they sit on a lot of coins, but they really did not need to cheat. In addition, the business is open source, so if there was a back door, they would have already boarded it ...

Hmmm .. like that from memory, something like 0.05 In a mining group.

Hmmm .. like that from memory, something like 0.05 In a mining group.

So let's make a small calculation ... rough estimates only ;)

0.05 On a day at the rate of $ 40 per bit, this is 2 $ and if we roll up, we will say 10 NIS per day.

The working card was told 20 hours per day for this and need ~ 100W extra at full load - exits 2 kWh or as per day

The cost of such a 2 hand card is about ~ 500 NIS and I assume a year-to-year life for such a card (second hand at full load - assuming no other component crashes).

So if we assume 300 a day of the year we are talking about 3000-300-500 = 2200 NIS per year if the Bitcoin rate does not rise radically ...

If you talk about 365 a day and the card holds more maybe you can get around the 3000 a year.

sounds logical?

However, it is clear that all the reactors expect the Bitquin rate to rise by hundreds of percent, and then this calculation is incorrect, but I assume that the percentage of mining will also be significantly lower ... The question is how much you will manage to cut until the jump is about to reach ;)

It's probably better to buy if you believe in Bitcoin's future, do not you?

If there are already other currencies that are likely to compete in Bitcoin, why not buy them if their value is currently thousands of percent lower?

The purchase will be a bit difficult because there are almost no sales, but you will be able to cut down most of them quite easily. And there is no guarantee that they will not disappear. There is hardly any trade in them.

As with any successful "business," there will be both good and less good competitors and substitutes.

Now it is left to find alternatives to Bitcoin and invest in them a minimum amount / time and wait ..

In the past year or two, various alternative currencies have been emerging. All are based on the same idea and almost the same software with different changes. Solidcoin, Devcoin, IXcoin, and more. Most of them sank anonymously because they offered nothing better than Who already sells and runs well. For a currency to be an alternative, it has to offer some advantage, or at least some difference. In country currencies (what is called FIAT) there is a geographical affiliation and that is enough. Global and digital currencies do not have the ability to attach a currency to a geographical area (and even if it was, for what?), So theoretically, if someone wants his currency to succeed, he should attract people differently. Maybe animated animation when you send and receive money? Or perhaps another method of keeping records that does not suffocate the hard disk with the accumulation of information?

First of all, thanks for the calculations. I never really bothered ;)

And beyond that, I do not run the mining 24 / 7 - it will kill me the computer or at least the graphics card pretty fast. Already today it reaches temperatures of over 85 degrees effortlessly. I run it mostly at night. So it already goes down to 8 for about hours.

In addition, there is another way to get Bitcoin, by using Sites that give you fragile bitcoin For clicks or video viewing, or a CAPTCHA solution, etc. So some of the Bitcoin I earned was in this way.

And as for buying, yes, better to buy - at least in terms of convenience. But who is really serious and ready to go on As a serious investment, you can risk investing in an ASIC computer for $ 1500 to repay themselves - as long as you get this computer fast enough. Games here on time. As time passes, the level of difficulty increases. You can think of it as a search for oil - there is a final amount of oil and another 30 a year will no longer be liquid oil, but only heavy oil that is harder to find, and even more difficult to produce products from it. So here as there are more miners, the difficulty level increases and at some point it will become a business of people with deep pockets only.
