Make sure that you have the correct hashrate suffix selected. The Break-Even Analysis feature can help you predict how long it will take to become profitable for a given setup. How is this calculated? Time to break-even is calculated by comparing your hardware cost which you must enter below to your predicted monthly profits and seeing how long until the initial hardware cost is paid off. The calculator also takes the changing difficulty diff change into account.
If the network difficulty is increasing quickly, this will greatly increase your break-even time. The diff change can be excluded from the calculation by toggling the "Use Diff Change" switch. Why is my break-even time 0 or never? If your break-even time is 0 you have likely forgotten to input your hardware cost below. If it is never, your break-even time has been calculated to be greater than 10 years. This is likely due to a large diff change value which causes your predicted profitability to turn negative in the future.
You could try lowering the diff change for a less agressive prediction or disable it altogether. Recurring costs are fixed costs such as rent or internet. This value, along with power costs are subtracted from your revenue to give profit.
Higher recurring costs mean lower profits and a longer break-even time. The profitability chart can help you visualize your long term mining projections. The chart can operate in one of three views: Total Profits The Total Profits view predicts what your overall profitability will be in the future. This is calculated by taking your current profits and adding them to each following months profits while factoring in the changing difficulty diff change , the diff change factor can be disabled.
This view assumes the price of the coin will stay the same. If you wish to account for a changing price ie if you think the price will rise in the future , switch to the "Coins Generated" view. Coins Generated This view looks at the number of coins you can expect to generate in the future.
This view does not account for any expenses, it simply predicts how many coins you will generate with your given hashrate and the diff change value. A high diff change will cause you to generate fewer coins in the future. Total Costs This view sums your power and recurring costs. It can be used to predict the total cost to operate your mine over a given period of time. Price Change allows you to factor in the changing price of the currency into your projections. You can use this to generate accurate best-case and worst-case projections for your operation.
Storing a bit word into the blockchain costs gas, which means storing 1kb of data costs gas. Just like the USD has cents, so too does ether have its own basic unit: wei. If we take wei as the basic unit of ether, we get the following table of definitions:.
Tip: use this converter to convert between Ether units. According to this informative site , the current average price of gas is 10 GWei 10 gigawei. That amounts to 0. Our smart contract could also have some logic, like summing or multiplying and then storing numbers, or triggers that activate on a specific mined block etc.
Obviously, storing data into the blockchain itself is incredibly expensive. Storage is better off in BigchainDB or IPFS , while blockchain is a better solution for global processing and verification of that data. All the gas prices of all the possible operations the EVM can perform are hard-coded in the Ethereum protocol and in the clients programs we connect to it, like Geth, Eth, Parity, etc.
More complex ones which call specific smart contract functions might run into hundreds of thousands or even millions of gas. The spent amount of gas is called gas cost. We, as a user, can modify the amount of gas we want to spend on a transaction and reduce it, but if the transaction runs out of gas during execution, we lose the gas we sent in.
On the other hand, if we provide more gas than is needed, the rest is refunded to us. Thus, the total cost of an Ethereum transaction is actually the amount of necessary gas multiplied by the price in GWei per gas unit. If we raise the price of gas to GWei, the transaction becomes proportionately more expensive:. A higher tx fee effectively encourages miners to process our transaction before others in the queue, thereby speeding up execution.
Gas is the unit of work expended per computational operation in the Ethereum Virtual Machine. For a smart contract which we want to deploy on the Ethereum network, two terms are important: gas limit, and gas price. The amount of gas actually required known only once the transaction has been executed is called gas cost.
Gas price is the price per unit of gas, expressed in GWei or billionths of ether.
Let's put these to work in a simple example: Say you originally bought your crypto for $10, (including $35 in transaction fees). Even though you only hold $9, worth of crypto after fees, your total cost basis is what you paid to acquire that crypto. Calculating Crypto Taxes with FIFO (First in First Out) - The cost basis for a sale is the cost basis of the earliest crypto that you acquired. To calculate the cost basis using ACB, you need to figure out an average cost for all assets. You calculate this by adding up the total amount.
