I want to bet with you that neither 1KufA3z7mLntENepGKo9Ktu9S7qAL2oLF3 nor 1F91HzJaQZ1WGU9NG2ZhFaXctZD6vMsV3L can be proven as owned by the owner of 1LfpedDQLqqEmSDZ9B7v2sPzz5NeeDhXec in any way by blockchain analysis. How much you want to bet ?
dr1980m tried to purchase 30 Gh by sending 0.003 BTC to 1F91HzJaQZ1WGU9NG2ZhFaXctZD6vMsV3L from 13RJvPMzxdAyzXQNnLAAimrMQBGseRJRmC.
which was later refunded from Cloud Mining Website's payout address (not the address it was sent to) as shown below:
1F91HzJaQZ1WGU9NG2ZhFaXctZD6vMsV3L is a deposit address provided to the customer by Cloud Mining Website (who confirmed that by giving them the refund). 1LfpedDQLqqEmSDZ9B7v2sPzz5NeeDhXec is obviously a shared wallet collecting incoming funds from individual customer addresses and I've already stated the reasons why.
Anyway, I'd like to hear an official response.
