i compiled a short list of what would happen if:
miners would be delivered end of September and the difficulty will continue to rise 25% every 11 days (re-target time)
In my opinion, this is the more pessimistic view... i'm guessing the difficulty increase will level off towards the end of the year.
The -Mining should have been mining hardware cost
EDIT: is there a site that shows how much the difficulty rose every 11 days and has a history?
EDIT2: this calculation is done @ 108$/BTC
This prediction could be accurate, and I'm a newbie with all this crypto-currency business so I probably do understand enough.
But with these predictions the difficulty reaching 4 billion in less than a year, what's realistically going happen to Bitcoin???
Could any or all of the following happen?
1. Miners play game of chicken and wait for some miners to switch off unprofitable rigs, hopefully making profitable again.
2. Bitcoin value rises dramatically especially because fewer coins are being found, hopefully making profitable again.
3. Compulsory transaction fees introduced to keep miners rigs switch on and hash rate's high for a more secure Bitcoin network, therefore making profitable again.
Don't forget cost of electricity. a 350GH/s Jupiter supposedly consumes 1000 Watts.
Also, the companies solely in the business of producing mining hardware going still be around when difficulty is in the multi-billion area.
