I think home miners quitting the mining business also has effects on the bitcoin economy as a whole. In the 2013 BTC boom hardware was solely bought with BTC, fuelling the rising prices of BTC. In 2013 und 2014 I spent most of my BTC at buying hardware. After my miners were obsolete in spring last year I did not need additional BTC. So I kept my BTC except some humblebundle purchases. So loosing the home miners is not a good prospect for bitcoin.
