PacCoin (PAC), or the People’s Alternative Choice Coin, is a lesser-known coin that’s been sitting since 2015. It experienced rapid inflation during 2017, which might be attributed to generous mining rewards. At the start of 2018, PAC had become one of the cheapest cryptocurrency coins out there, with a relatively large total supply of roughly 3.5 trillion coins and a planned cap of 100 trillion. It has a devoted community that hopes to see their holdings come to fruition and make them rich, believing in its future as an “Internet penny” that lends itself to micro-transactions. PACcoins started to trade at 0.0000$ as of only a couple of days ago. Later on, the coin gained some on its price with a couple of increases that helped the price jump from non-existent to existent. After the latest decrease that made the price drop for over –9%. This decrease led to the current price of 0.000031$, which is still better than having the coin traded at 0$. For now, it remains uncertain what will happen with PACcoin and how well this coin will perform after being re-launched three weeks from now. For now, we strongly advise to give this token a thought and consider investing – the price is still too low, so even if the coin drops again, you won’t be losing much money.
Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
