ethereum-blockchain-data

With Bitcoin’s blockchain data files already over 50 GB in size and Litecoin’s blockhcain size approaching 7 GB there are some concerns rising about the rapidly growing in size blockchain of Ethereum. While BTC and LTC are already a few years old and established and used crypto currencies, Ethereum is still fairly new and in just little over 3 and a half months the blockchain size has already reached 2.9 GB in size. Now, imagine what will happen in a few years of use with the adoption rate and numbers of transactions increasing… it could easily catch up to the size of the Bitcoin’s blockchain. In fact the amount of data that the blockchains of crypto currencies take is starting to become an issue for everyone that is running a full local node and things will get worse as crypto currencies will need more and more space to store the data on your hard drive. This will make online wallet services and light wallets more attractive, but we do still need a lot of full nodes running in order to secure the network of any crypto currency. So not only the matter about the block size for Bitcoin should be discussed, but also the matter about the total blockchain size and that goes for other crypto currencies as well. It is even more of an issue with crypto currencies such as Ethereum that have faster block times, making them generate more blocks in less time.

ccminer-1-7-tpruvot-benchmark

The latest release of the ccMiner 1.7 fork by tpruvot (source) has added some new interesting functionality among which is the ability to run a benchmark on all of the supported crypto algorithms by the software. There is no more need to go through all of the algorithms one by one and record the returned results, all you have to do is run ccminer.exe --benchmark and the miner will go through all of the algorithms automatically and print out the hashrate you get with your particular Nvidia GPU. It can work with single and multiple GPUs in the system, but if you have more than one and you do not specify which one you want tested it will benchmark all of them and display individual hashrate. Thanks to the ease of use of this feature and the fact that it needs just about 5 minutes to run we might soon start seeing crypto hashrate benchmarks included in Nvidia GPU reviews on sites that do hardware reviews, but generally do not bother to test crypto mining performance.

Since the output in the console when you run ccMiner in benchmark mode is quite big, you might want to automate the run and have the results written to a text file by default that you can later open and view more easily than having to scroll in a console window. To do so and have the results written to benchmark.txt file just run the following command line: ccminer.exe --benchmark > benchmark.txt

Here is a sample benchmark run on a GTX 980 Ti GPU:

*** ccminer 1.7 for nVidia GPUs by tpruvot@github ***
Built with VC++ 2013 and nVidia CUDA SDK 6.5

Originally based on Christian Buchner and Christian H. project
Include some of the work of djm34, sp, tsiv and klausT.

halleybtc-investment-plans
A new service called HalleyBTC was just recently launched that offers high ROI for its Bitcoin savings investment options. The service is apparently operated and backed by one of the large Chinese Bitcoin mining farm operators – Halley China (though it seems that it could be ZeusMiner/ZeusHash instead through some partnership with Halley China), so that is apparently where the interest for your investment is coming from. While Halley China is not open to international investors (their website is only available in Chinese), it seems that the new HalleyBTC service is targeting a broader English speaking audience. They have definitely launched the new service right on time as with the recent jump in the price of Bitcoin there is a lot of increase in user’s interest in different ways to invest in Bitcoin.

The service offers three types of investment options, the first one is called Current Deposit and it gives you 0.02% daily interest with no fixed period. The other two higher return options are for 30-Day Fixed Deposit with 15% expected APY (Annual Percentage Yield) and 90-Day Fixed Deposit with 17% expected APY. The higher interest rate is ensured by the fact that your investment is being locked for a specific term, so apparently the Bitcoin you invest on the long term can in turn be used for investment in the existing Bitcoin mining farms of the company to increase the mined coins for example. There are a lot of tools and services that can improve your investing. You just need to pick one that is right for your personal investment style. For example, if you are comparing Motley Fool and Morningstar, you should focus on which service is ideal for your personal needs.

halleybtc-bonus
For their launch HalleyBTC is running a special promotion giving each new user the chance to get 1 to 10 Bitcoins as a bonus deposit to start your investment. All you have to do is register a new account and click on the Get Bonus button on the main page. Do note that what you get as a bonus investment in BTC cannot be withdrawn and will be in your account for 10 days only, what you get to keep is the interest rate you accumulate on the amount for these 10 days. The idea is to get to try and see how the service works without having to invest any of your own Bitcoins up front, do note however that this promotion is only valid up to November 8th November 15th, so do take advantage of the offer before actually sending any of your own coins!
