As far as chips go, have you already received the chips from AM (24 PH worth) and what was the power consumption per Gh (you mentioned some could consume 33% less power than stated by manufacturers)? In other words, have you already bought the chips while the BTC value is relatively high?
Chips will be purchased when capacity is ready and the IPO is deemed successful. This means at significant lower prices with more efficient boards and chips. But of course we have current AM BE200 and other chips available for testing.
In the Prospectus theres no mention of bitcoin price going down between IPO and deployment. IF this happens, will each unit represent less kW? Will the 20% extra hash be deployed to help with ROI if the BTC value does go down? Will the fee's be decreased?
Infrastructure and hardware is purchased in fiat money. To minimize risks, the funds will be managed well and safety buffers have been built into pricing.
For infrastructure development, the most sensible approach is to immediately exchange BTC for USD, as as this investment needs to be made first and prices are relative fixed.
For managing BTC/USD for actual hardware, a sensible approach will be followed to bridge the short time between IPO and hardware acquisition.
How will we individually as unit holders decide to reinvest (percentage) vs. no reinvestment? is this a shareholders vote with a majority needed to decide the reinvestment or will the DataTank give us to buy additional "units" with the mining dividend?
As 100% of the income is paid out, it will be an individual decision if you reinvest at a later point when the market changes. DataTank Mining will NOT keep income as reserve for re-investment. 100% is paid out.
4. With scrypt mining, will you establish a different type of shares? When would you offer this, if it becomes a separate unit? or will scrypt mining capacity be included in the DTMA/DTMB?
DTMA and DTMB holders can deploy new boards by either directly purchasing hardware from DataTank Mining (at cost) or third parties and mailing hardware in. New funds may only make sense if the hardware development is not yet completed or a certain scale needs to be reached to be economic. However, pre-orders in form of commitment (no-down payment) may be a more sensible option, assuming that DataTank mining is an attractive client to chip manufactures due to the scale involved. This will be a community approach.
Will ROI be measured in fiat or BTC?
It will be measured in the currency that is being mined. Initially BTC in the case of DTMA. DTMB will be up to the individual miners using the capacity.
