I have used blockchain.info as a place to store one of my wallets for many years now. It has never been compromised. Every time I log into the wallet I am required to verify I am logging in via an email sent. Nearly all of my logins over the years have been from my laptop at home. This past weekend when bitcoin hit 60k while visiting my parents (on their secure wifi) I logged in to blockchain.info on my phone (updated google pixel phone) via the chrome browser. I had to verify my log in attempt in my email as usual. At 8:36am I saw my balance, an all-time high, it was there. I used my phone, as usual for a few minutes, checked on the news feed. Checked text messages. A few minutes later I went back to the blockchain page to look at the balance again and it was zero.  The one outgoing transaction took place at the same time I was logged in and using my phone.

My phone is updated with the latest security patches and I don't have Russian or Chinese ringtone apps on my phone.

Any ideas on how this happened?

I recently switched out my motherboard to the ASUS B250 mining expert board. The board works well, but I need help from someone that is running SimpleMining OS (SMOS) from a USB stick. My SMOS USB stick, which worked fine as a bootable drive on the last MOBO, isn't being recognized by the B250 mobo.  The board can recognize a Windows 10 SATA drive and boot from that just fine but I need some help to get it to boot from the USB drive.

Does anyone know the proper bios settings to get the B250 to recognize the USB drive and be able to boot from it?

Thanks for any help

If I set the overclocking power limit in SMOS to 200 it will use that power limit for a larger card like my 1070 and then apply a default power limit to smaller cards. I think my 1050ti get's applied a 75 watt power limit automatically (which seems to work fine) and it will apply a 140watt limit for the 1060 6gb. Under this setting the 1060 produce about 300 sol's and use 2.45 watts according to the SMOS console window.

When I drop the power limit on the 1060's to underclock and save some energy the exact opposite happens. I will set the power limit to 75 watts for the 1060's and they produce less sols as expected but the console says they are using more watts. now they show up at 260-280 Sol's but are using 3.65 watts according to the console.

How is that possible? Lower power limit, fewer sol's (that part makes sense), but more watt's. Clearly I am not an electrical engineer.

Is the console watt reading and AVG watt display accurate?

To make things more confusing when I allow simple mining apply the default wattage to the 1060's cards the cards run hotter and the fans spin at a loud 80% or higher and draw the lower 2.45 watts. When I set the power limit to 75 watts. The cards run cooler and the fans spin at around 30% which makes sense (cooler = lower fans) but the cards are drawing about 1 watt more when compared to the card running with the fan screaming away 80%+. That doesn't seem possible. A card that is cranking it's fan to the max uses fewer watts than a card with the fans barely running?



Any explanations to this weird watt usage and tips to have these cards run quiet and efficient would be greatly appreciated.

I have set up my first mining rig. Very simple cheap rig as a test run. The mother board I used has an HDMI out which I used to set up windows etc. When I placed my first GPU into the board and booted up nothing came out of the board HDMI anylonger. Hmm. Makes sense I guess. So I put the HDMI into one of the GPU cards and i could see the computer again.
A few questions here...

Where do most people get their video out from their rig? on the board? a single GPU card? Which card? Does it make a difference?

Does it slow down the mining on the card to have an active HDMI powering a 4k monitor coming out of it? It has to right?

Does it help the GPU out for mining if the HDMI is unplugged from the GPU after mining has commenced? If so is there a difference from this than just turning off the monitor/tv?

Thanks for any help

If you were able to buy a new bitmain miner would you buy the S9 or L3? And why?
