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?
The Bitmain S19 has 110Th/s
On average if you solo mined with one Bitmain S19 (110TH) you would hit one block about every 30 years (assuming constant difficulty)
In the real number interval [0,1], any specific number has zero probability of being picked (assuming a continuous probability distribution).
Here's one:
0.4895739579579407964907
Hey, I picked it! I'm so lucky, right?
That's what happened to the lucky miner who got 6.25 BTC so soon. It was pure luck. The probability of you and me getting this lucky is practically zero, as was his.
Few understand this.
My L3+ mined a LTC block about a year ago for a pool, at the time it would have taken 435+ days (probability) to solo mine. For $400 worth of power during a probabilistic time period I couldn't chance a solo endeavor. The S19 takes about 4X the power I cannot fathom how one could solo mine with any expected outcome unless they are actually a farm that has 500+ machines.
