pretty flat for this jump. will stay flat as long as btc stays low. reasons are simple most hashing is done by the builders and margins are too tight for them to build out.
yeah there might be profit as low as 300. but if you are running a 30ph setup and it has paid itself off.
the 30ph gets 431 coins a day. if your power is 5 cents and you use .6 watts a gh you spend 18mw a day that is 900 a day in power . 431 coins are 163000 a day
so after power your profit is 162000. take salaries a few other expenses and that plant earns 150k a day. you don't need to expand. if you keep coins flat and diff flat you just make big money day after day.
the interesting thing here is home miners can survive in this model.
they need .8 watts a gh and 12 cent power with 3% growth and 380 usd coins .. those numbers you do roi.
and if you could pull off 2% diff jumps you make pretty good money.
