I have been GPU mining and holding ZEN for the past year. I like the coin but have amassed quite a few - close to 1000. I am nervous about what the price might do when the ASICs hit the scene. I am contemplating trading them all to BTC as a relative safe haven to see what happens. Am I being paranoid or is there a potential for the price to drop a lot when this happens?

I sent some BTC back on December 7th from the blockchain wallet to my Trezor. Blockchain was my first wallet and I no longer want to use it so I was trying to move everything over.

The fee was too low and it never went through. If I look up the transaction it says removed/expired. https://www.blocktrail.com/BTC/tx/1bf2c9222419661cf9d5497a73b641069bf9260b96cc838aa42fc18b2cd7a29e

I don't care if it goes through or just goes away as I have access to both wallets and could resend with a higher fee. My problem is in my blockchain wallet it shows as pending with no options. I can't cancel, resend, or anything.

I did some reading on here and got electrum and imported my keys into it thinking somehow I could solve the problem there but it seems to have the same issue. It shows as pending in there. I have heard you can do a double spend with a higher fee but electrum won't let me spend them it says not enough funds.

What can I do to remedy this? Again I don't care if the transaction confirms or if it just goes away and I can resend with a higher fee. Right now the funds are just stuck in limbo.

With stocks you have people who buy them and are “long” and make money when they go up and people who sell them short and make money when they go down. I certainly would not want to short bitcoin but is that even possible? Stocks are kind of held in equilibrium because people want them to go up and down so they can make money depending on their position. With bitcoin it seems the huge upswings are in part due to no one wanting it to go down. Everyone who invests wants it to go up or am I wrong?

I have a bunch of mining proceeds on a hot wallet. About $3000 US but it is comprised of a ton of small transactions. I was going to move it to my trezor after being spooked by the nicehash incident. Using their recommended fees it was going to be $1000 to send.  .

I am no rush for this I don’t care if it takes a week. What kind of sat/byte should I choose?

After dinner while sitting around the table Bitcoin came up. I explained it to everyone and several were really interested. I had a few of them download the Blockchain wallet to their phones and sent them $5 of BTC to show them how it worked and then showed them my daily earnings from my miners. I think they are hooked and I will be helping them get more involved soon.

I am mining ZEN with 48 cards. I currently have my payment threshold set at 4 ZEN and I get a payment every day. I don't have any immediate needs for the ZEN it just sits there for now. The way I understand it more frequent payouts result in more transaction fees when I go to sell? Is once a day payments good I should I make it once a week or something?
 

I have mining rigs with 6 1070's each. I have been slowly building these and now have 8 of them. Heat is becoming an issue. No so much the cards overheating but they are overheating my house.

They are in a 12 x12 room that has a window and a door to the outside. I never use the door. I was thinking of taking the door off and putting plywood over it and then building a huge box inside the room to put the miners in connected to the plywood on the door with a fan sucking cool air from the outside in at the bottom and blowing hot air out at the top.

Will this work? I am open to suggestions. I spent a lot of time and money running adequate electricity and hardwire ethernet to this room and want to keep them there but the heat is so bad now that it is not just heating up this room it is heating the adjoining room which is my bedroom.

Anyone follow this guy?

Stumbled onto his You Tube channel and the guy seems brilliant. I have been watching a lot of his videos and he has written several books. Seems to me like one of the most knowledgeable people on bitcoin I have came across.

I have been devoting several hours a day to learning about bitcoin over the past month and this guy seems to be the most knowledgeable I have encountered thus far.

I just purchased a trezor and set it up. My plans for this are ultra safe storage of a decent sum of BTC for a long period and not using it on a day to day basis.

I have read through how it works and watched a half dozen you tube videos but I am not sure how to securely verify my seed words should I ever need to use them. It seems you can do a restore but that involves typing them in on your computer which doesnt seem safe if your computer is compromised.

Then again using the device without testing the seed restore process doesn't seem to safe either.

Any recommendations?

I am mining both ZEN and ZEC but prefer to hold BTC. I have been trading them on bittrex. Is there a better or cheaper way?  I have also been trying to determine the best frequency to do the exchanges. I am mining about $50 a day. Should I exchange daily, weekly, only when rate is favorable?

I have read dozens of threads saying you need to keep your BTC on a hardware wallet or paper. Anything online isn't safe they say. When trading that is not really feasible is it? I like to move in and out of positions several times a day and often at a moments notice. My trading account has a sizable balance (to me - 5 figures)  in it.

How risky is this and any additional things I could do?

I am researching ideas to set up a small farm. Most have a cool and a hot side with cool air being brought in on one side and hot air exhausted on the other. The miners though are just sitting on shelves in the middle.

What if you made a room with a plywood wall dividing it in half and cut square holes in the plywood and slid the miners in the holes so the room was effectively sealed between the hot and cold sides with the only airflow between the sides being through the miners?

You could have a big fan sucking cool air into the cool side and a big fan pushing hot air out the other side.

Thoughts?

Finally got my first two rigs running with nvOC. They each have six GTX 1070's. How do these numbers and temps look?

Didn't want to pollute the nvOC thread which is mostly filled with technical advice on the OS.

I have two 6 GPU EVGA GTX 1070 rigs running nvOC v19.

My settings are core 100 / memory 1000 / power limit 110.

I am getting 183 MH/sec @ 55 degrees. Works out to 30.5 MH per card. It is rock stable.

I have no idea if this is good or bad and if my settings are good? Seems the windows and Linux clock setting are way different.

What settings re you using and are my hash rates what I should expect? Seems my temps are really low and maybe I could be pushing them harder? 

Each rig pulls enough watts that you can really only safely put one per typical 15 amp household circuit.

I am in the process of mounting a 100 amp sub panel in my mining room with eight 20 amp breakers and eight outlets each on an individual breaker. The sub panel is going to be connected to my main panel with 4/3 wire rated for 70 amps. Should be able to easily handle 8 rigs.

Was curious what others were doing.

I have read through some threads and the consensus seems to be if you mine coins you owe tax on the value of the coin the day they were mined. Then if you later sell them for USD you owe taxes on the gain if they went up from your basis.

I don't fully understand this. Does a commercial fisherman pay taxes on a fish when he catches it or when he sells it? Does a farmer pay taxes when his crop grows or when he sells it? Heck we planted 20 pecan trees at our house. When they grow to about ten feet tall they can be sold for a around 1k each. Do I owe taxes for growing them?

I can't wrap my head around the taxation just for mining a coin. Seems it would only be a taxable event if you convert it to Fiat or spend it.

I currently have an Avalon 741 and two GPU rigs on order. I am in the process of setting up the room they are going to be located in. From what I gather these miners want to be plugged into Ethernet and don't use wifi. Our broadband connection and wifi router are on the opposite side of the house.

What are my best options? Should I run an Ethernet cable through the attic to a switch in the mining room or is there some sort of switch that I can put in the mining room that will connect to the wifi and provide Ethernet ports to the miners?

Not going to happen any time soon but eventually the difficulty will be so hard that it is no longer profitable. Even if technology advances to where it is what about when all 21 million are mined?

We have seen the slow down in transaction times recently when people pulled off to mine BCC.

I know there are transaction fees but they are not that lucrative. When the big boys pull out of mining and there lots more coins in circulation how will the network function? Will it be super slow or transaction fees ultra high to keep it going?

Again I don't see this as any immediate concern but what about in ten years?

I am building my first miners. Ordered the parts today for two 6 GPU gtx 1070 rigs.

What is my best option on the software side? With windows I would need to buy two copies right which is not cheap. EthOS at $39 seems attractive.

I have not messed with Linux in nearly 15 years but in the late 90's early 2000's I was a system administrator for about a dozen Linux and Unix machines so they don't scare me but I am rusty as heck. Last version I think I used of Linux was Red Hat 8.0.

I am new to this but have built a ton of computers and am pretty tech savvy. I currently have an ASIC mining BTC.

With the upcoming difficulty bomb looming for ETH is it worth it to spend the 3.5k or so to build a 6-8 GPU miner? No one can predict the future but is it reasonable to expect this to remain profitable long enough to see ROI?
