NiceHash has announced its plans to start reimbursing all users that were affected by the security breach that happened on December 6th last year starting this Friday, February 2nd. The NiceHash Repayment Program will initially reimburse 10% of the old balance amount to all users that were impacted by the security breach. NiceHash will continue to periodically repay the remaining amount to all users in the coming months untill the full amount from the old balances is paid back. The old balance will be repaid in Bitcoins (BTC) and not in the fiat value or any other cryptocurrency…

Repayment program for internal wallet users
Users that were registered on the NiceHash platform before December 6, 2017 can log in to their account and can see their old balance tab under the Wallet section on their Dashboard. The old balance shows the total amount of Bitcoins (BTC) that users had on their wallet address prior to the attack. This balance will be fully reimbursed by NiceHash to users current balances, starting with the initial ten percent of the total amount on Friday, February 2, 2018. Registered users should enter the Repayment program by clicking the “Enter repayment program” button on their Dashboard. Users will be notified about all future payments in advance.

Repayment program for external wallet users
Users who were not registered with NiceHash at the time of the attack and were using the NiceHash service with their external wallet address will also be reimbursed in the same way as internal wallet users. External wallet users can go to the following page and enter their external wallet address (that they were using at the time of the attack) to see their old balance. This balance will be fully reimbursed by NiceHash to users external wallet addresses, starting with the initial ten percent of the total amount on Friday, February 2, 2018. Users will also be able to monitor repayment progress on the miner page.

Conditions for payment to external wallet addresses do apply with the Repayment program. When you reach 0.01 BTC you are eligible for payment. NiceHash will include your old balance in this amount. For example, if your old balance (that is going to be reimbursed) is 0.009 BTC, you still have to mine an additional 0.001 BTC to this external wallet address so you reach 0.01 BTC in total. Once the combined balance shows 0.01 BTC, payment will be made to your external wallet address.

Every time you get new PCI-E risers for a new GPU mining rig you may be surprised with build varying build quality and that can affect the stability of the system you are building. Even when the quality is fine there is another common problem that the standard PCI Express risers using USB 3.0 cable printed upwards exhibit – they have the tendency to move a bit in the slot and even at times disconnect. This can cause a bad connection or even a broken one and one or more of your GPUs suddenly disappearing from the miner and you starting to wonder what happened and diagnosing the whole system to find the culprit.

Fortunately there is a simple solution available if you have a 3D printer or a friend with one that can help you print a small and simple, yet very effective PCI-E Riser Lock. The 3D model is available for free on the Thingiverse website made by a user called totembe who is accepting Vertcoin tips from happy users of his creation. The simple plastic clips that you can 3D print hold the small PCB with the PCI-E x1 connector very tight to the PCI-E slot on the motherboard, so that there is no more play and the chances to have these getting disconnected are becoming pretty slim.

The PCI-E Riser Lock take just a few minutes to print and use just about 1 gram of filament and are really useful. You can clip them on both sides of the PCI-E slots, for example if there are some components preventing you from attaching the lock on the front of the slot, then just clip it on the back, it will work. The only slots that you cannot attach these locks are the ones that come with metal shielding/strengthening as they do not have a place to attach the lock to. Also some mining motherboards with more than the usual number of PCI-E slots such as AsRock H110 Pro BTC+ will not work as the slots there are too closely spaced to each other.

Do note that the design of the 3D printable PCI-E Riser Locks is not compatible with the newer designs of the PCI-E risers that have slightly larger x1 PCI-E PCBs and angled USB connectors, but then again these do not seem to suffer from the same issue of getting disconnected as the older design with the USB cable pointing up. It is possible to modify the design of the locking adapter to also work with these relatively easy, but as we’ve said already it might be pointless to use these anyway. We are yet to see similar problems with the angled USB connector risers as with the straight up USB ones, and as you already probably guess the USB connector and cable pointing up is what is causing the problems.

If you are a small crypto miner and not a large mining operation you may find it very hard to acquire up to date Bitcoin ASIC miners as the demand is still pretty high and the wait time is long. If you manage to find an ASIC miner is stock the chances are the price will be significantly higher as they are being resold with serious profit by people that prefer to make money this way instead of mining with the devices. At the moment there are pretty much 4 main manufacturers of Bitcoin ASIC miners that sell to end users and in small quantities and as you might expect they do not have anything in stock as the wait time is in months.

1. Bitmain AntMiner S9 (13.5 THS)
Bitmain is the most popular name among the ASIC manufacturers and probably the biggest one as well and even they are struggling to have stock of the AntMiner S9 ASIC miners they produce. It is interesting to note that the S9 has started shipping in the summer of 2016 and is still their top product. Bitmain has already sold all of their production up until the end of March, so when they release a new batch it will be scheduled for delivery sometime in April earliest.

2. Canaan AvalonMiner 821 (11 THS)
Canaan has been making their Avalon miners for years, though they were a bit slower in terms of specifications as compared to Bitmain and not as popular among end user miners. Their latest AvalonMiner 821 was announced in December last year and just started shipping its first batches for people that have preordered early. You can currently preorder AvalonMiner 821 for shipping/delivery in the second half of March, so you can probably get these a bit earlier than if you wait to preorder an AntMiner.

3. Ebang Ebit Miner E10 (18 THS)
Ebang’s Ebit miners are mostly popular in Asian countries, though they are trying to get to a wider market and their latest announcement of a 10 nm ASIC miner – the E10 made some waves. It is however an expensive device and still hard to get with a minimum purchase quantity of 20 units and all batches already sold through the end of March.

4. Halong Mining DragonMint 16T Miner (16 THS)
Halong Mining is a newcomer that just recently announced their plans to enter the Bitcoin ASIC miner market to try and fight with the market dominance that BitMain already has. They are still yet to start shipping their first devices in March this year and you cannot currently preorder units on their website with new batches probably to be available for April earliest.
