from BA website:
Hosting starts in May 2014
Wait. What?
God, I hope they don't mean it for existent pre-2014 orders.
Dear Black Arrow LTD, can we get some clarification here on cloud mining starting date please?I.M.O.
If you ordered Cloud mining in 2013 and it's paid for,you will be fine. Remember the Minions used for "Rent" and those for building X-1/X-3 all come from the same "Batch" of chips.
When the delivery date changed to Mar/10,so did the "Rental" date. This new date would apply to those wanting to place an order now.
