Some tools are often used in the daily work of mines, and readers often look for mines and ask where to find some mining-related information. Mining mine thinks it is a good idea to share these practical tools with everyone. Today we will introduce the useful tools or websites for querying the following information.
1. Mining machine static payback period
2. Shutdown currency price
3. Daily theoretical output per unit computing power
4. Prediction of difficulty changes in the next difficulty cycle
5. The current best handling fee
7. Cumulative increase in 60 days
……
9. Long-term coin hoarding addresses and high-frequency trading addresses
9. Rich list
Next, Mine Mine will introduce the corresponding query tools in the above order.

There are many websites that calculate the static return cycle of mining machines. For example, minbi.com and BTC.com, etc. Here we use minbi.com as an example.

As shown in the picture above, the mining machine price is 19,200 yuan/unit, and the electricity fee is 0.38 yuan/kWh. The current static payback period of Antminer S19 is 376 days.
You can also choose other currencies on this page, such as Ethereum, etc. Such as calculating the payback cycle of the Sapphire 5600xt 8 card machine.

It should be noted that the static payback cycle of the mining machine assumes that the future mining difficulty, currency price, mining basic rewards, miner fees for packaged transactions, electricity charges, etc. will remain unchanged and the mining machine will continue to run at full computing power. Calculate the payback period of the mining machine. In fact, these factors are changing almost at any time. Therefore, when making investment decisions, the static payback period cannot be regarded as the actual payback period of the mining machine. It is more appropriate to use it as an indicator for reference in decision-making.
2. Shutdown currency price
The shutdown currency price is also an indicator that miners are very concerned about. The shutdown currency price represents the safety margin of the mining machine. This indicator can be queried through the Minbi mobile APP.
Open the mining coin APP, click "Calculator" in the lower right corner, select the mining currency at the top, and enter the computing power, power data and electricity price of the mining machine in the blue box to calculate the shutdown currency price.
The calculation on the left side of the figure below is the shutdown currency price of S19 PRO; the calculation on the right side is the shutdown currency price of Sapphire 5600XT 8 card machine.

Some clarifications need to be made about the shutdown currency price:
The shutdown currency price is just a reference. For mining machines with low safety margins, such as S9 and S11, the reference significance is greater. For machines with high safety margins, such as S19 and M30S++, such machines have machines with low safety margins as a buffer Pad, the calculated shutdown currency price is very inaccurate, and the reference value is not high.

3. Daily theoretical output per unit computing power
The value in the red box in the above picture is the theoretical output of BTC with 1T computing power for 24 hours. This is the theoretical output of the FPPS model, including the part of miners’ packaging transactions.
Miningbi.com can also check the theoretical output per unit computing power of dozens of mining coins such as BCH, LTC, ETH, ETC, and ZEC, as shown in the figure below.

5. The current best handling feeimage description
How is the current best handling fee calculated? The relevant person in charge of BTC.com said that there is an algorithm behind it. Simply put, the current best handling fee is based on the average transaction fee of the last few blocks, and the transactions in the transaction pool to be confirmed (transactions waiting in line for packaging) Calculated in real time, the transaction paid according to the current best handling fee on BTC.com will be packaged and confirmed in the latest 1 to 2 blocks.
Ethereum Fees
There is also a handy tool: Gasnow.

The upper limit of the Gas Limit of each block is 12.5 million. Different types of transactions require different amounts of gas. Common ETH transfers require 21,000 Gas, and complex contract transactions may require several million Gas. Therefore, each block actually requires The number of packaged transactions varies, with a minimum of dozens or even a few transactions, and a maximum of more than 600 transactions (12.5 million/21,000).
The calculation method of GasNow, the first step is to list all 2000 transactions in the queue to be packaged (tx1, tx2, tx3, tx4,...txn...tx2000), and then arrange them according to the Gas price from high to low. The N transactions (tx1, tx2, tx3, tx4...txn) that can be packaged in the next block, note that N here is uncertain.
On this basis, we calculated these four numbers, and their meanings are as follows: "Extreme Speed" mode represents the gas price of the median transaction (tx1, tx2, tx3, tx4...txn); "High Speed" is the Gas price of txn; "Normal" is the Gas price of the max(tx2n,500) transaction; "Slow" is the Gas price of the max(tx5n,1000) transaction. If the next block can package 300 transactions, that is, n=300, then "normal" means the gas price of the 600th transaction, and "slow" means the gas price of the 1500th transaction.At present, wallets such as imToken, MYKEY, MathWallet, and TokenPocket have already supported the function of Gasnow. When using these wallets to initiate transfers, there are four types of fees to choose from. Below is an example of imToken wallet.secondary title
6. Cumulative increase in 60 days
, which is obtained by adding up the gains of each day in the last 60 days.
www.qkl123.com/data/acc_increase/btc
The logic of this indicator is: a bear market is created by a bull market, and the rise in currency prices requires continuous support from newcomers and new entry funds. New funds generally flow in steadily with the spread of news and the effect of the bull market getting rich. To a certain extent, if the existing users in the market exhaust all their funds, or even add a large amount of leveraged investment, the price will rise sharply in the short term, and the speed will exceed the speed of new funds entering the market. The new funds cannot support the rapidly rising price, and the currency price will eventually collapse at a very high position with huge potential energy, ending the bull market and starting a bear market.
Now, this index is easy to obtain on QKL123. In addition to BTC, there are also cumulative gains of ETH and BCH; and there are also 7 days, 30 days, 60 days, and 90 days for reference.image descriptionsecondary title

8. Long-term coin hoarding addresses and high-frequency trading addresses
Are you a long-term hoarder or a short-term speculator? Wondering how many people share your style? blockchain.com provides this data. It divides all addresses into three categories: long-term holders, medium-frequency investors, and high-frequency investors. The proportions of these three BTC addresses are as follows:

Here are a few fun tools to introduce.
Which address has the most bitcoins, and which are the exchange addresses in the rich list? tokenview.com can satisfy your curiosity.
The first place on the Bitcoin rich list is the cold wallet address of Huobi Exchange, which has stored more than 140,000 bitcoins, with a current value of more than 2.1 billion US dollars; the fourth place on the rich list is the cold wallet address of Binance. This website can also query the rich list of dozens of cryptocurrencies such as ETH and BCH.
