Bitcoin network hashrate has increased significantly in the past months, pushing up the difficulty and lowering BTC/TH/Day prices for SHA256 hashing power purchase. In order to make bidding for SHA256 hashing power more accurate and competitive, we'll be switching from TH to PH units for SHA256 hashing power purchases.

This change has no affect on mining if you are a seller (provider/miner) of hashing power. UPDATE: in case you're using price setting in the stratum password parameter on your SHA256 miners, then you'll have to adjust this setting accordingly after we switch to PH units. If you're a buyer you'll have to take this change into account while placing new SHA256 orders. For example, instead of current price 0.0029 (in units BTC/TH/Day) you'll have to enter 2.9000 (new unit will be BTC/PH/Day).

The switch to the new units will take place on June 1st 2016 at 00:00 UTC.

Existing orders, which will be placed and not completed before the switch will be automatically converted to the new units - no action will be required from you. However if you have some automated applications/scripts, utilizing automatic placement of new orders, you'll have to change them accordingly to make them compatible with the new units.

Effectively, these views/functionalities for SHA256 algorithm will be changed:

• first page table (TH -> PH)
• order list (TH -> PH)
• order details (TH -> PH)
• new order (TH -> PH)
• API methods: stats.global.current, stats.global.24h, orders.get (price in PH, limit in PH), orders.get&my, orders.create (price, limit in PH/s), orders.set.limit, order.set.price

Please keep in mind that this changes applies only for SHA256 algorithm, all other algorithms will be unaffected. And again, this change has no affect if you are a seller (provider/miner) of hashing power.

Therefore we kindly ask you to please keep in mind the June 1st 2016 at 00:00 UTC if you are a regular SHA256 hashing power buyer to make sure that placement of new orders will be in line with this small change.

Thank you for using our service!
