Right now he has 68*900 = 61k Tied up which could buy a lot of hash rate imho.
If $61,000 is causing Ken to delay getting miners then this venture is over. Please think about what you just said:
100TH/s makes more than $61,000 every single day! Why would Ken delay us a entire week or month because he wants $61,000 worth of miners more!
Every two weeks we lose 20% - 30%, that is losing us about $13,000 a day if we had 100TH/s in the main production run!
Come on people think and do the math!
Why delay our venture and lose more in a week because of a missed difficulty that we save waiting to spend 61 bitcoin!
Ken is meant to have at least $100,000 ready for miners plus the $1,000,000 worth of Bitcoin to buy chips, if he delays us because of $61,000 we will lose that because of just one difficulty delay, let alone two!
Please get out a calculator and do the math!
