I believe NEM could be in for a big year in 2018. Their tech is better suited for business than ETH (as much as we all love ETH) and their superior security is going to attract serious business ventures, not just those looking to make a quick buck.

2 great examples are LoyalCoin and Qchain. LoyalCoin is looking to become a singular rewards points that all multi-national companies can use, rather than collecting many different points at many different stores. I know personally, I hate keeping track of many rewards cards in my wallet and I end up just not using them. This is a great use of blockchain technology to solve a problem and make our lives easier.

Qchain is a blockchain-powered native advertising and sponsored content sales platform. They want to build a suite of open and transparent applications that provide decentralized and secure solutions for digital advertisers, in-house marketers, content publishers. The advertising industry is plagued by distrust and fraud, which makes it ripe for disruption by the transparency and trust induced by the blockchain.

2017 saw the rise of many great companies launch on Ethereum, which no doubt was related to it's epic rise over the year, but as more legit businesses start coming up on NEM, I think 2018 will be the year you want to own NEM.
