Good question @reklamapsy
I don't believe network will stop simply because it's not profitable. Anyone who is mining I'm sure is aware of it takes time to get your money back on a mining investment. Overtime the value of BTC will go back up and the 200 day return period can actually be cut even shorter(depending on how fast the value goes up) Haha i guess what i'm trying to say is yes. Real cowboys mine even at a loss. Keep the good questions coming, maybe we can get others involved and spark a conversation. Cheers :)
