Oeh,

ärge sinna lihtsalt sellist raha pange, mille kaotamist te endale lubada ei saaks. Lihtsalt sellepärast, et mõni mees suure hurraaga omale paari kilotonnist SMS laenu kaela ei võtaks, või midagi veel hullemat.

[GinPenGuin]

Deadlock, jah, pole mõtet panna sinna liigset raha alla.

Küsimus: kui panna kokku üks masin selle Bitcoini kaevandamise jaoks, mida mul vaja oleks, et saada selline keskmise võimsusega (ei teagi väga mis suurusjärk on keskmine). Ja mis see maksma võiks minna?!

Ise masin kokku panna on vist ohutum kui tellida sealt Butterflylabsist (esiteks nad on tarnega viivitanud ja teiseks kui mull lõhkeb, siis pm on prügimäekaup)?!

[reints]

keskmine on vast 2x7970

Neid ASIC scämme on jube palju, väga rämedat raha on inimesed kaotanud, lootuses kiiresti enne teisi kergelt rikkaks saada.

Diesel157, A-lvin, endal väga ei karga pähe mõte osta kuskilt netist endale see ASICS või see teine (jah, küsisin korra, kas tasuks osta)... Mida võiks teha, on panna kokku üks ise. Kui midagi juhtuma peaks, siis saab videokaardid ja asjad maha müüa pärast.

reints, Hmm, see on mingi 700€ siis jah:)?! Mis veel vaja on? Emaplaati, protsessorit, kõvaketast ja mälu?

[reints]

Tervet arvutit millel on vähemalt 2 video kaardi tugi kui üldistada

[Go Kane!]

Praegu 2 kaardiga ilmselt suht pointless hakata kaevandama, eriti kui difficulty tõusis ja isegi vennad kellel 10.-neid kaarte käes ei saa normaalseid tulemusi hetkel.

Kõige kasumlikum oleks olnud osta siis kui teema aktiivseks läks.

Samas proovida ju ikka võib!

[GinPenGuin]

-cocain-, reints, ma tegelikult niisama kalkuleerin, et mis võiks maksta üks ehitatud masin, mis toota ka suudaks. Ma poodi asjade järele ei torma !

[limp]

Mis see adekvaatne mhash/ghash kiirus peaks olema, et kasu hakata tootma?

tsitaat:

meepstah explains how bitcoin basically works (and why it´s probably too late to get rich) As someone who's taking an interest in the technology behind Bitcoin, I'll give you a short overview. 1.The coins are "mined" by folks crunching numbers. You can mine your own bitcoins by having your computer (specifically, your graphics card) solve some equations. 2.The integrity of the network is preserved by a running log of everything everyone ever did (meaning, from the first coins mined to the last coin spent - it's all written down in a journal). 3.The network is secure because accounts are protected by private keys and the SHA256 algorithm used to protect the contents is (currently) more or less impenetrable. 4.The transaction log is nearly impossible to fake out because if you try to do something you're not technically able to (as in, transfer coins from an account which doesn't hold enough), your transaction is flagged by a disagreeing node as invalid. The transaction is then passed around until a consensus is reached as it its validity; if less than 50% of the nodes think you should be able to make the transaction then it is voided. 5.The algorithm is self-correcting for mining rates, meaning that the first guys to crunch a few numbers got coins every 10 minutes and now that thousands of people are mining with fast hardware, it's become more difficult so that the 10 minute average is maintained. 6.The coin supply dwindles two ways. First, the number of coins per solution goes down over the years. It was 50, now it's 25, eventually it'll be zero around 2140. Second, the chances of solving a block and the returns for doing so diminish greatly as the work is spread around to more and faster computers. Just ten days ago, my mining computer could find .12 bitcoins per day. With this bubble and/or boom going on, more people have started mining and I'm down to about .075. So, why is it valuable? Well, like someone said below, I might as well be the one to say it - money is only worth what we agree it's worth. Federal currency ($USD, for example) has a huge structure behind it to try to maintain its value, and some folks think it's unsustainable. Bitcoin has no such structure. You can't issue it any faster than the algorithm allows. You can't print more, you can't spend it if you don't have it (yet, wait for banks to get involved on this one), and you can't steal it if it's properly secured. This makes it every bit as safe as the $USD in terms of storage and security, and quite a bit more secure than the $USD in terms of safety from administration. The fed cannot print another million bitcoins, only a few years of mining can do that. Scarcity is built into the system. So, is it a ponzi scheme? Yes, in a way. The very early adopters hold hundreds, even thousands, of the coins. At current market rates, they're probably slowly selling them off for literally millions of dollars. The thing is, they've created a monster...whether or not the intent was to get rich on a ponzi scheme, the bitcoin currency still exists and it's still secure. If they cash out, the decentralized nature of Bitcoin means that it still exists and can still be used. So what's bad about a currency that allows you to very quickly transfer value from one account to another regardless of nationality, location, and social standing? Well, the worst part from an investor's point of view is that it's completely and utterly new. Nothing like this has ever caught on before. It's been around for four years, people have had a long time to poke holes in the security, and it's matured into a valid commodity. So to answer your question directly: In the last few weeks, there has been a media blitz. Some of it was intentional and some of it was not (big cheeses in the financial industry are commenting on it; that garners a lot of attention). As people notice it, they want a piece of it (however small) "just in case" it goes crazy for real. This forces the bubble to grow. Nothing is forcing the bubble to pop, either: If the million or so Bitcoin holders today dilute their holdings out to ten million total people, the value will increase roughly by an order of magnitude (simple supply and demand). That means if you have a bitcoin you bought at $200, it'll technically be worth $2000. The coins are divisible and transferable down to 8 decimal places so the currency can support a fairly massive unit value. Again, the new nature of this means every prediction you read is pure speculation. It could crash tomorrow, or an investment bank could try to buy up half of it. Either way, I'm riding it out with a few coins just in case I become an accidental millionaire. Hope this clears it up a bit. It's really pretty interesting and there are tomes of information to read if you want to learn more. Cheers! Why do you mine and what are you mining? Mining is the process by which we confirm the transactions and make sure no one's cheating. The more miners you have, the safer the network of coins is and the harder (or, further past impossible) it is to make an invalid transaction (i.e., moving coins you don't have). The current reward for mining is new coins. Eventually the reward will be much smaller, dwindling to a tiny fraction of each transaction so that people are still willing to mine. The system taxes itself to pay a bit to those who work for it.

Tänase äripäeva paberlehe tagaküljel on kah üks artikkel bitcoinist "Bitcoin kui uus üleilmne valuuta?". Veebi pole seda ülesse pandud.

[salatoimik]

Ma siin mõtlesin et peaks endale kh 1 kasti vaikselt tiksuma panema. Tuleb siis palju tuleb.
Kõige kasulikum vist keldrisse panna tiksuma. Siis jaguneb elektriarve terve maja vahel ära (60 korterit)

Hetkel ei näe veel hinna kukkumist ette. Asi töötab ju põhimõttel, et nõudlus suur ning müüki vähe, mis hinda kergitab. Seega hind kukub ainult juhul, kui mingi uudis tuleb ja inimesed ära hirmutab(uued ja vanad tegijad), ning kõik kiiresti müüma hakkavad. Tuleb palju BTC müüki ja hind kukub kolinal, kuna tahavad võimalikult kiiresti rahaks BTCid vahetada, seni kui neil veel mingit väärtust on.
Hetkel järjest tõusev hind, aga meelitab ligi palju uut verd ja tähelepanu BTC tõuseb jällegi, mis omakorda tõstab jälle hind, kuna nõudlus kasvab. Mining muutub jälle mõtekamaks, kui €20 asemel saad €200 tulu. Muidugi selline tõusutrend ei kesta igavesti ja mingi hetk muutub BTC lihtsalt liiga kalliks, et ostjate hulk kaob ära ja eks siis näeb mis juhtuma hakkab. Need kellel varasemast ajast BTC, need müüvad, uued tulijad ja vanad, kes loodavad kõvasti vahelt saada ostavad kuniks on lootust ja mõtet. Nagu mäest üles sõitmine nõrga mootoriga, mingi hetk ei pinguta enam välja ja edasi ei lähe, siis veered jälle alla tagasi.
Ise ka muidugi kahetsen, et ei ostnud . Oli selgelt ette teada, et hind üles läheb. Muidugi ei oleks nii kiiiret kasvu julgenud prognoosida, kui hetkel.

Dow Jones ja S&P 500 on samuti kõikide aegade kõrgemail. Võib ka juhtuda, et kui seal asendub pulliturg karuturuga, siis tõmmatakse bitcoin nii muuseas kaasa. Ehk siis kõik müügiks. Aga tegelikult ma kaldun arvama, et bitcoin lõhkeb siiski väga lähitulevikus, kasv on liialt eksponentsiaalne olnud juba viimase nädala jooksul. +100% 1 nädala jooksul pole ilmselt paha teenistus.
