DigiByte (DGB) is a rapidly growing world-wide decentralized payment network & highly scalable blockchain, inspired by Bitcoin. DigiByte allows you to move money over the internet similar to PayPal & Western Union but with many improvements, including lightning fast transactions with minimal or no fees. You send & receive DigiBytes to or from any DigiByte address in the world in a matter of seconds with no required sign up, registration, or hidden fees. DigiByte is the 1st coin to fork to multi-algorithm mining for more fair distribution, with 5 unique algos & independent difficulties a 51% attack is significantly mitigated and becomes much harder to carry out, also the 1st coin to develop & implement DigiShield (asymmetrical difficulty adjustment).

Primecoin (XPM) is a fairly new alternative cryptocurrency that introduces a new type of proof-of-work in peer-to-peer cryptocurrency designs based on searching for prime numbers. Up until now most alternative crypto currencies rely either on SHA-256 like Bitcoin or Scrypt like Litecon for their proof-of-work design and Primecoin brings something new and interesting on the table making it a potential contended for the third place in popularity among coins, though it is currently more like the last one in the top 10. Primecoin’s Prime Number Proof-of-Work has been designed less than a year ago by Sunny King who tried to make a new and interesting alternative crypto coin and he did very well. Primecoin is the first cryptocurrency on the market with non-hashcash proof-of-work, generating additional potential scientific value from the mining work. This research is meant to pave the way for other proof-of-work types with diverse scientific computing values to emerge.

What is interesting about Primecoin is that the currently available miners are only CPU-based, so there is room for improvement going to GPU and then to specialized hardware mining hardware. That is if Primecoin is to follow the path that Bitcoin has already paved and that Litecoin is already following. The fact that Primecoin (XPM) uses different proof-of-work method means that you are not able to mine it the same way as Bitcoin or Litecoin and if there are going to be ASIC miners made for Primecoin they are going to take some time. Not to mention the fact that at the moment you can combine Litecoin and Primecoin mining on a single system – the CPU will mine XPM and the GPU will mine LTC, good combination for some extra profit and full utilization of the hardware you might already have.

Litecoin (LTC) is the second most popular peer-to-peer digital crypto currency released as an open source software project after Bitcoin has gained quite a lot of popularity. Similar to Bitcoin (BTC), Litecoin generation and transfer is based on cryptographic proof-of-work scheme and is not managed by any central authority and is relaying on a P2P network consisting of the users that are mining the crypto currency. Litecoin is intended by its developers to improve upon Bitcoin, offering new improvements and relying on a different crypto algorithm that made it a popular alternative to Bitcoin. Litecoin was released in 2011 by Charles Lee, a former Google employee, who used the Bitcoin-Qt client as a basis, bud modified it in order for the Litecoin to have a decreased block generation time, increased maximum number of coins, different hashing algorithm, and a slightly modified GUI.

What made the Litecoin very popular and the second-largest cryptocurrency by market capitalization at the moment is the fact that it was one of the earlier alternative crypto currencies that offered both differences and new things that set it apart from the competition. But the most important thing was the fact that it is a Scrypt based and not SHA-256, making it ASIC-proof or with other words not being able to mine LTCs with the already available Bitcoin ASIC miners. This brought back the GPUs as the primary mining solution for generating Litecoins, something that has been left in the past by Bitcoin, so you can say that Litecoin is following in the footsteps of Bitcoin. Another way to look at the to crypto currencies is if we compare the Bitcoin to Gold and the Litecoin as Silver.

Much like with Bitcoin, Litecoin also has a lot of alternative crypto currencies based around its basic code and concept, in fact LTC has much more alternatives that cannot be mined with Bitcoin ASIC. And the fact that Bitcoin ASIC miners are so powerful nowadays there is not much point in releasing SHA-256 based alternative crypt currency similar to Bitcoin, it is better to have it based around Litecoin and scrypt, though lately we are seeing announcements for upcoming Litecoin ASIC miners later that year already. Some of the more interesting and notable alternatives to Litecoin that are also Scrypt-based are: FeatherCoin, WorldCoin, DogeCoin, Lottocoin and many others appearing all the time, though a lot of these don’t get much attention from the users and die quickly.
