bitcoin-wallet-smaller-transaction-fee

By default the sending of Bitcoins from your wallet is set to use a minimum of 10000 satoshi as a transaction fee in order for your transfer to be processed faster, for bigger BTC transfers the fee also increases. The problem however comes when you want to send smaller amounts of coins such as a few hundreds of satoshi where a fee of 10K satoshi is significant. The latest Bitcoin Core wallet 0.10.0 comes with an advanced menu to control transaction fees and you can take advantage of that easy to use feature to send smaller BTC transactions with lower fees and still have them processed fast. You can of course try to send some coins without any fee, however that may result in very long time needed to confirm the transaction, so it is not recommended, especially if you are paying for something and want to receive the service or goods faster, so you might want to avoid doing that.

One of the ways to save about half of the standard fee and still have the transaction processed very quickly is to use 10000 fee per kilobyte of transaction data, so normally you would pay about half of that for small transactions. It may take just a bit more time to process these transaction than with the normal 1K fee, but they are processed very quickly as well. Alternatively you can go for the minimum possible fee of 1000 satoshi for a transaction, but that could be slow as well, though it is still better than not to pay a transaction fee at all.

miner-control-kbomba-mod

The Miner Control tool, successor of NiceHash Control that has been developed by StuffOfInterest, is a useful piece of software for Windows users that want to make it simple and easy to mine the most profitable coin or rent their hashrate for the maximum profit without much effort other than setting thing up initially. The author of the original tool however hasn’t been working on it and adding new features for a while, not that the software is not useful enough as it is, but there are still some things that can be improved and added to make it even better. Thankfully the development has been picked up by Bombadil who has released his own improved version called KBomba-Mod (source) that adds some extra features and has further improved the tool. The best thing is that his modified version is fully compatible with the original config file, so you can just add the configuration that you are already using to the latest Miner Control v1.6.4 KBomba-Mod and it will work. Then you can start experimenting with his additions without having to waste any time to migrate to the new version.

amd-opencl-dlls

If you are using AMD Radeon-based video cards for mining crypto currencies you have probably noticed that some algorithms have issues with various video driver versions or the performance you get may differ between older and newer version. Since the AMD miners use OpenCL there is an easy solution that can help you deal with driver version issues and to get the optimum hashrate for a specific algorithm. There is not need to reinstall the complete video driver, you can just copy the OpenCL DLLs from the respective driver version inside the same folder where the software miner is (cgminer or sgminer) and when you run the miner it will load the different OpenCL version, regardless of what video driver you have installed. Do note that you need to delete the compiled kernel BIN file for the respective algorithm or algorithms when replacing the OpenCL DDL files in order to get the kernel recompiled with the different version. You can download the different AMD Radeon drivers OpenCL version 13.12, 14.4, 14.6 RC2, 14.8, 14.9 and 14.12 in a single package from the link below and try out what performance you will get by replacing the DLL files inside the miner software’s folder.
