HOdlcoin (HODL) is a relatively new experimental altcoin that can only be mined with the CPU for the moment using the coin’s wallet and although it is a PoW coin you get interest on your wallet balance and there is an option for deposit with even higher interest rate. The algorithm of the coin is made in a such way that early adopters holding their coins in the wallet get higher interest rates with the idea to attract more users resulting in a wider coin adoption for a shorter period of time. The regular interest rate is 5% APR, but with the extra bonuses and deposits the interest can grow exponentially. The deposits work in a way very similar to PoS, though there are some differences, your coins are locked for a period of your choice and the longer the deposit, the higher interest rate you get. To check the current interest rates and bonuses you can visit the HOdlcoin Interest Rate Calculator.
The coin uses 1GB AES Pattern Search Proof of Work algorithm that involves filling up RAM with pseudo-random data, and then conducting a search for the start location of an AES encrypted data pattern in that data. Pattern Search is an evolution of the ProtoShares Momentum PoW, first used in MemoryCoin and later modified for use in CryptoNight (Monero, Bytecoin), Ethash (Ethereum). For the moment you can only mine HODL coins with your CPU via the wallet, there is no separate miner available yet or a pool where you can mine the coin. This means that you will have to run a separate HOdlcoin wallet on every computer where you want to be able to mine the coin and since it is solo mining luck can also play big role in how much you might be able to mine.

Some people have asked is there is a CPU miner for Decred (DCR), well it turns out there actually is – a version of tpruvot’s cpuminer-multi CPU miner (source) with added support for the Blake-256 14-rounds algorithm used by Decred and support for getwork as the coin does not shave support for stratum for the moment. We have compiled a Windows 64-bit binary for the miner that you can download and try below if you are interested in mining Decred with CPU, although there might not be much point in doing so based on the performance you should expect to bet getting out of the CPU miner. Currently Decred (DCR) has a very high network difficulty and slow block times, so it is not easy to mine with GPU, let alone with CPU. Trying out the CPU miner we are getting around 1.55 MHS per thread on a Intel Core i7 5820K (6 cores 12 threads) for a total of about 18 MHS versus 1.2+ GHS from a GTX 970 or 280X GPU. Still if you want to experiment CPU mining Decred (DCR) you can do so with this miner.

Revisiting the Coin Magi (XMG) CPU-only Altcoin
28, Jan 2016
We haven’t paid a lot of attention lately to alternative crypto coins that are mined only with CPU with no GPU, FPGA or ASIC miners, so we’ve decided to check what is going on with Coin Magi (XMG) as we haven’t been following it actively the last few months. Coin Magi is a PoW and PoS coin that is currently being traded for a little over 2000 satoshi per coin, it is being traded on multiple altcoin exchanges including some of the largest ones, though the trade volume at the moment is pretty low and there are multiple pools where you can mine the coin if you do have some spare CPU power available and you are wondering what to mine.
Coin Magi (XMG) uses the M7M algorithm and besides CPU mining and staking coins you can also rent mining rigs at the Mining Rig Rentals service. Last year we have tested the most up to date miner available for XMG – the Wolf0 m7m v2 cpuminer on an Intel Core i7 5820k CPU and now we have retested again in order to compare it with a more recent release in the form of a dedicated m-minerd for XMG (source) that is based on Wolf0’s code. The 32-bit version is significantly slower, so we do recommend to go for the 64-bit miner for best performance, but interestingly enough we are getting slightly less performance for, the new miner. The advantage that the new m-minerd miner for the M7M algorithm has an option for that allows you to set the percentage of CPU usage you want the miner to take.
Intel Core i7 5820k (6C 12T) CPU:
– Wolf0 minerd 64-bit – 122 KHS
– m-minerd 32-bit – 64 KHS
– m-minerd 64-bit – 119 KHS
