Thanks for this thread Igorr. It provides a perspective we don't often see here. I'm a bit confused as to how the decreasing mining profitability will drive down price though.
When bitcoin lose the support of mining hardware manufacturer, then game iz over,
and bitcoin returning to the beginning.
It is very simple,
If you have a lot of money (mining company) it is easy to manipulate and speculate with a price.
manufacturers mining hardware with cheap ASIC-s chip earned a lot of money.
Now mining factor is 4.6 cents per Gh at 24 h and game is over,
will no longer be no one to artificially increase the bitcoin price, and it go to 10-30 usd.
