So. If I buy a Jupiter now and mine just ONE BTC with it and BTC rises to 10k I won't be in profit?
Not if you paid with 70 bitcoins. It would mean you lost $690,000
If I bought a jupiter NOW (which is a fucking long way from 700k because NOW BTC are more like 140 dollars NOW), then they RISE to 10k dollars each (which a shitload higher than their 140 dollar current value) and I managed to mine just one BTC when I got the fucker..assuming I didn't leave it sitting in it's box for years ...I'd be not only in profit but better at maths and comprehending english than some people here.
I made the numbers extreme and round to illustrate a point so it was easy to understand. Waste of time.
I think hes saying that if you kept the 70 bitcoins, and never bought a jupiter, then youd have 700000 $ once the bitcoin hits 10k$. If however you manage to mine more bitcoins than you paid for it in btc. Then buying the miner would have been the better desicion, rather than just holding on to the bitcoins.
Say you manage to mine 100 btc, Thats 1000000 $. Anything under 70 btc, and youd have been better of keeping the coin instead of buying the miner.
