What makes you think that  

Tell ya what...send me the miner first i will put the bct in escrow (reputable person here) and i will pay you $2500.  Bam more money for you, sweet deal right....

but out of stock everywhere 

*************************

Just curious, what is the going rate on Powercolor rx 570 4GB versions?

hehe i also am just curious i wont yell at the OP but it's true, SOMEONE is footing the bill

hey OP if i may ask what arrangement do you have? apartments and other things please think about more than the cost, the STRAIN on the grid is something a place may AGREE on paper too, but not REALIZE what their agreeing too. dont wanna burn down your arrangement haha

So much for freedom of speech around here eh?

Is he stealing if the electric comes from the sun? Wind? Water?

By your reckoning half the planet is either a) stealing, or b) leaching

By my reckoning your post and my reply are a waste of electricity, I guess that makes us both wasters lol

also dont forget to get better collersytem if you want to start a farm to cool down temperature of the asics/gpus
this will increase you earnning 

Edit: placed order with CC, will post some feedback and pics of the miners once they arrive  .

DagCoin: a cryptocurrency without blocks

Back in 2012 I thought a lot on a new cryptocurrency that could merge the concepts of transaction and block. Each transaction would carry a proof-of-work and reference one or more previous transactions. The resulting authenticated data structure would be a Direct Acyclic Graph (DAG) of transactions where each transaction “confirms” one or more previous transactions. The confirmation security of a transaction would be measured in accumulated amount of proof-of-work referencing (or confirming) the transaction. This structure is well suited for a cryptocurrency without subsidy (such as a side-chain). On the past years I’ve read a couple of similar proposals on bitcointalk (although I cannot find the references now). When the GHOST paper was published, I perceived it as a reinforcement of my idea that a tree could give more security than a chain in case of high rate of transactions.

My open problems…

The problem that I could not solve in 2012 is how to limit the maximum cut of the generated DAG or, in other words, how to prevent all new transactions from referencing the same set of parent transactions. How to create the incentive to “move forward”? The DAG must not increase in “width”, and it should look more like a DAG-chain. Also one must prevent users from choosing old transactions to extend the DAG. I tried several monetary incentive structures to force users to choose newer transactions, but with no result. To know the last “ledger state” there must be a way to consolidate branches. Merging branches should be good, but not too good such that everyone starts merging the same branches over and over. The problem of spam was also less important, as no transaction would be able to get a “free ride” in a block, as each transaction carries PoW. Ultimately the owners of a computer that is being part of a spamming botnet would realize their computers have been hijacked based on the amount of CPU consumed. For instance, if a transaction requires a proof-of-work that takes 1 second in a standard PC, and each transaction is 400 bytes in size, then a botnet consisting in 10K computers may create transaction reaching 3 Mbytes/second. This high network bandwidth usage itself is not a problem, since it can disrupt the network only as long as the attack is active. However, there must be a way to prevent the DAG-chain from growing at that pace. It turns out that the election of an optimal data structure allows the DAG-chain to be compressed, but it requires us to change how we think about double-spends, and how we conceive the “ledger state”.

A Radical Change

The leap of faith required to find an out-of-the-box solution is to think about double-spends not as a boolean attribute, but as a probabilistic attribute, based on comparing the confirmation work on competing transactions. An the security of a transaction, as the confirmation work compared to the the work expected that an adversary may use. Also it requires to forget about the concept of a “global ledger state”. In Bitcoin there is a global ledger state. Chain reorganizations can always rollback the state, but the state is globally consistent. There is a certain probability of the last block rolling back, but the probability is the same for every transaction in that block. In this proposal, the ledger state is just the overlap of all possible transactions, each with its own confirmation probability, and there is no consistent global state.

Design Premise: “The cryptocurrency network benefits from creating a DAG growing as “thin” as possible.”

In other words, having the average maximal cut as low as possible. It seems that referencing many previous transactions (high out degree) can make the DAG thinner only if the following transactions reference the transaction with high out degree, but are themselves of low out degree. So we want high out degree some times, but low out degree another times.

I designed a DAG that tries to fulfill that premise, and an associated incentive structure such that:

 There is a benefit for users to reference as many previous transactions as possible
 Referencing many previous transactions is incentivized only when there are many previous transactions unreferenced.
 There is no competition between users to reference a previous transaction.

WOW.  im going to try not to be offended on your total fucking ignorance, but here's some TRUTH:

THAT is Canaan's official site, the OP linked the CORRECT link.
Second:  THESE motherfuckers made the VERY FIRST ASIC CHIP EVER!!!! B4 BItshit which seems to be all you fucking noobs know about.
The miners ARE profitable, and WAY MORE RELIABLE than BITMAIN's chinese trash, i have OWNED personally Avalons and they are GREAT machines and STILL alive today 4 years later, and i know MANY happy Avalon 721 owners (their newest machines)
They are NOT as efficient or as powerful as bitmains garbage because the string design Bitmain uses is super unsafe and will prob burn down IF it even last 5 months.

Get your facts straight, these guys are THE OG's of ASIC chips you nubs

we really have to start asking questions such as is the situation really bad

just some time ago we were happy the gaming platform allowed bitcoin and i gifted my cousin games with it..

Today it takes 1 day to confirm and the gift arrives late, the fees are more than the actual game I bought my cousin

The future does not look good for bitcoin and the alternatives are gaining strength day by day.

Hope things go well for bitcoin
