Autoswitch · SHA-256 and Scrypt

Mining pool with autoswitch

Q: How often does autoswitch change the coin?

Not on a schedule but on events: profitability is recalculated on every new block in the pool networks. If another coin has become the most profitable, the ASIC moves to it right away with the next block of that network. If the leader stays the same, the ASIC keeps mining the same coin.

Q: Is hashrate lost when the coin is switched?

No. The ASIC gets new work at the moment it would receive a new job anyway because of a new block, so there are no extra reconnects and no stale shares caused by the coin change.

Q: Do I need to change the pool address or port on the ASIC?

No. There is one stratum address per algorithm, and the coin and autoswitch mode are chosen in the dashboard. The ASIC is configured once.

Q: Can I exclude a coin from autoswitch?

Yes. In the worker settings you can mark coins autoswitch will not switch to — it picks the most profitable of the rest. And if you turn autoswitch off, the worker mines the one coin you choose.

Q: Which autoswitch mode should I choose?

If you sell a little at a time or hold your coins, choose “Real”: the price of the best buy order. “Deep” suits most miners. If you sell a large volume at once, choose “Deepest”: coins with a thin order book will not look more profitable than they are.

Q: How is income credited if the ASIC mined different coins?

Each coin is credited separately for your work in its network, merged coins as a bonus to the primary one. The pool sends a coin to its wallet from the dashboard once the balance reaches the minimum payout, and pays the transfer fee itself.

Q: How much does autoswitch cost?

There is no separate charge for autoswitch — the regular pool fee applies: 2.9% to start and down to 0.4% with the grade system.

Q: Which ASICs work with autoswitch?

Any SHA-256 and Scrypt ASIC — Antminer, Whatsminer, Avalon, Elphapex and others: the pool switches the coin, not the firmware, so there is nothing to configure on the ASIC.

Hash-Hut autoswitch keeps your ASIC on the most profitable coin by itself. The pool watches blocks, difficulty and exchange order books across all its networks and switches your hardware exactly when profitability changes — not once every few minutes like timer-based switching.

Autoswitch is also called auto switch, auto-switching or profit switching — it is the same thing: you point the ASIC to one address, and the pool decides which coin to mine.

On block
switching the moment a new block arrives, not on a timer: One address
per algorithm — no ports or pools to change on the ASIC: 3 modes
of order book price depth — for any selling volume: 15
primary coins in autoswitch, merged coins as a bonus

How to enable autoswitch

What is autoswitch in mining

The profitability of coins on one algorithm changes all the time: difficulty is recalculated after every block, rewards change and exchange prices move. Right now one coin pays best for a SHA-256 ASIC, an hour later it is another one. You cannot follow this by hand, and repointing the ASIC to another pool or port every time is inconvenient and costly: you lose time and some shares.

Autoswitch solves this on the pool side. You connect your hardware once, and the pool calculates the profitability of every coin and gives the ASIC work for the best one. Merged coins are mined as a bonus on top of the primary one, so your income comes from several networks at once.

How Hash-Hut autoswitch works

The pool runs its own blockchain nodes and is notified of every new block in all networks — its own and those of partner pools.
After a block the coin profitability is recalculated: the block reward and current network difficulty show how many coins the hashrate earns per day.
The number of coins is multiplied by the price. The price is not the last trade but comes from the exchange order book at the depth you choose — this shows what the coin is really worth when you sell it.
If another coin has become the most profitable, the ASIC gets work for it right away — at the same moment it would receive a new job anyway because of the new block.
That is why switching costs no hashrate: no extra reconnects, no waiting for a timer and no shares going stale because of the coin change.

Block-based autoswitch vs timer-based switching

Many multipools and auto-switching tools check profitability once every few minutes. Until the timer fires, the ASIC keeps mining a coin that is no longer the most profitable.

	Timer-based	Hash-Hut
When it switches	Every N minutes, whatever happens in the networks	When a new block arrives and profitability has really changed
Losses on switch	The ASIC reconnects or drops its work — seconds of mining and some shares are lost	New work replaces the next regular job, hashrate does not drop
Coin price	Often the last trade price, even if your volume cannot be sold at it	Price from the buy order book at the chosen depth
Coins to choose from	Only the coins of that pool	Pool coins and partner pool coins, plus merged coins as a bonus
ASIC setup	Often a separate port or address for the switching mode	One stratum address, the mode is chosen in the dashboard

Price depth: real, deep and deepest mode

The price of a small coin may look high until you try to sell even a few thousand dollars worth: the order book is thin and the price drops fast. That is why Hash-Hut autoswitch takes the price from buy orders, and you choose the depth.

Real
Price of the first buy order (best bid). Fits if you sell a little at a time or hold your coins.
Deep
Price of the order that fills a small one-time sale. A good middle ground for most miners.
Deepest
Price of the order that fills a large one-time sale. For big farms: coins with a thin order book will not look more profitable than they are.

Which coins autoswitch chooses from

Autoswitch picks the primary coin within your ASIC algorithm: SHA-256 switches between SHA-256 coins, Scrypt between Scrypt coins. Any of them can be excluded for your worker.

How to enable autoswitch

Sign up on Hash-Hut — it takes a minute.
Set the pool address for your ASIC algorithm and the worker as “login.name”. The password can stay empty.

If your equipment is located in Russia, you can mine to this address even under whitelist-based blocking. This address should be reachable via the MegaFon provider, but you can try it with others as well.
If you are logged into your account, then here will be shown your USER_STRATUM_ID
In the dashboard open “Workers”, tick the workers you need and click “Configure” on the panel at the bottom of the screen.
Choose the autoswitch mode — “Real”, “Deep” or “Deepest” — and exclude coins you do not want to mine if needed. Nothing has to be changed on the ASIC itself.

To have autoswitch on for every new worker, choose the default mode in “Settings”. In the “Off” mode the worker mines the one coin you pick.

Autoswitch questions

01What is autoswitch in mining?

Autoswitch (auto switch, profit switching) is automatic switching of an ASIC to the most profitable coin of its algorithm. The pool calculates the profitability of all coins and gives the hardware work for the best one, so the miner does not have to watch prices and difficulty or reconfigure the ASIC.
