What if the coin goes DOWN?

Can you profit buying the coin (shorting BTC is very difficult from what I understand) if the exchange rate drops? A miner can.

Purchase miner for 0.75BTC. Mine 0.375BTC. BTC goes down to say $100. You have 0.375BTC worth $37.50.
Don't purchase miner, keep the .75BTC. BTC goes down to say $100. You have 0.75BTC worth $75.00.

No matter what happens with the exchange rate of BTC or whether it goes up or down, 0.75BTC is always more than 0.375.
At this point I simply refuse to believe that anyone can be this obtuse or ignorant. You must be trolling.

I thin it's YOU who is trolling...

BTC @ $600(USD) I Buy 1 coin
BTC @ $600(USD) I buy mining equipment for 1 coin

BTC @ $550(USD) My one coin is worth $550
BTC @ $550(USD) My mined amount can go OVER $550 because I can mine 1+BTC with it.

Are you so obtuse or ignorant that you cannot understand something this simple?

So you're finding the magical miner that makes more BTC than it's initial outlay. Not one BFL device did that. Not one Cointerra. Not one Hashfast. Not one Black Arrow. None of the Avalon B3s.

THe first 2 Avalons, the first KNC Jups, and the first S1s did this.

Dragon, Rockminer, SP30s won't.

Good luck.

you are assuming quite a bit saying a dragon will not do roi in btc. it could. you have no idea of power cost for someone. put in 1th with 0 power cost it will get a lot of coins.
also there is a power wall for asics. and it will be reached when it is reached growth will slow to a crawl.

if power wall is .2 watts diff will max near 600g since no one could earn money even with 8 cents a watt.

and if the power wall is .35 watts diff maxes near 400g at 8 cents

so at a diff of 600g and free power the dragon keeps earning money.

So free power people with smaller rigs will never disappear.

I made roi with s-1's purchased in may

3 for 1.15 btc how did i do it. power at an 84 % discount. 14 cents a kwatt cost me under 2.5 cents. So I will never be fully pushed out of mining due to my power discount.

Well you're obviously the exception to the rule. Maybe the OP was overstating it by saying it's "impossible". But the sentiment is still true for 99% of us.

yeah spot mining at home with a power discount will work.

figure ways that the heat works for you not against you.

make deals with people that have access to low power costs. >>>> big upside if you find them..

I have the one spot 14 cent power is discounted 84% down to 2.24 cents.

I must not run more then 800 watts.
I must make the gear quiet.
There are places that s-3's will pay to run.
I know of 2 developments near my home in Howell NJ that use electric power to heat their home.

Old school baseboard heat heating bills are 300 a month in small 4 room homes.
I am attempting to have s-3's mining in one or two of these homes. This could make nice money for me and the home owner's that I recruit.

While Antminers aren't known to catch fire, be careful with extending out your liability to other people's homes. It's one thing to mine in your own house and keep an eye on your equipment. It's another to have somebody else's home go up in flames due to a power supply failure - and that probably won't be covered by the homeowner policy.
