Any mining expert can disclose how many machines or how much it currently would cost to set up a mining arrangement that produces 126 Terahashes (TH) of mining power?
1 th earns .2296 usd a day
10 th earns 2.296 usd a day
100 th earns 22.96 usd a day
126 th earns 28.93 usd a day1000 th earns 229.60 usd a day
10000 th earns 2296.00 usd a day
100000 th earns 22960.00 usd a day
1000000th earns 229600.00 usd a day
1260000th earns 289,300.00 usd a day just about 1 block if rewards were .15 btc as 6.40 x 44000 = 281600
so he earned about 10,000 days worth of coin rather than 1
best machines to get exactly 126 th would be say 3 antminer t17 units or 2 whatsminer m20s units.
So basically it was hitting a 10000 to one shot.
Which means that, at the reference difficulty level, it can be expected to happen every 10,000 blocks * 10 min/block = 100,000 minutes.
That is, once in 70 days - or 10 weeks.
Definitely not a once in a lifetime event, if Philip's numbers are correct.
