The thing that I can't calculate into this, is the fact CryptX is selling off old hardware, not sure where this extra btc is going. Two speculations:
1, Will go to pay down loan as comes in
2, Will go to reinvestment, if this one the % decrease in div week to week should be les than 7% but without knowing numbers can't guess.
If i remeber well the sell of old hardware will repay the initial 500TH buyed to replace himself, so basically if i have understood well, the first 500TH were paying themself by the selling of the old hardware.
Cryptx can confirm ?
