Grin coin is a private & lightweight open source project based on the mimblewimble blockchain implementation. MimbleWimble is a lightweight blockchain protocol proposed by anonymous author that goes by the name Tom Elvis Jedusor (inspired by Harry Potter) in July 2016. Since then, the proposal has gained a huge following among Bitcoin and privacy advocates. Unlike bitcoin or ethereum, there are no addresses in Grin. In order to transact using Grin, both wallets must communicate with each other online with the results broadcasted to the network. Another key different is that transaction history (sender, receiver, amount) will not be recorded on the blockchain. Due to the removal of these information from the transaction, the data size remains small and that keeps the blockchain lightweight. New nodes can easily join the network without having to download a large blockchain. Grin coin was launched without an ICO, fundraising, or pre-mine. Developers around the world contribute openly with the goal to ensure the coin distribution remains as fair as possible. There are 2 popular wallets widely available to interact with the Grin network.

There are 2 hashing algorithms involved with Grin. Cuckoo-29 is meant for GPU mining while Cuckoo-31 is meant fo ASIC mining. This is a deliberate design to encourage miners to eventually move into ASIC mining for efficiency while keeping it fair at the beginning of the launch. Grin coin has launched its mainnet on 15th January 2019 and is now available for mining and trading.
KuCoin is an international cryptocurrency exchange based out of Hong Kong that currently supports the trading of 210 digital assets. What’s unique about KuCoin is that they share 50% of their overall trading fee revenue with users holding their exchange-based token. In a similar fashion to Binance, KuCoin offers relatively low tradings fees and incentives for holding (or trading) its native cryptocurrency. Back in 2011, the founders started researching blockchain tech and went further to build the technical architecture for KuCoin in 2013. 4 years later, the exchange launched with the ultimate goal of “becoming one of the top 10 worldwide hottest exchange platform[s]” by 2019. As stated on their official website which lists 12 core members, “Kucoin aims at providing users digital asset transaction and exchange services which are even more safe and convenient, integrating premium assets worldwide, and constructing state of the art transaction platform”. CEO and founder, Michael Gam, is a former technical expert at Ant Financial, an affiliate company of the Chinese Alibaba Group. He was also a senior partner at Internet giants like MikeCRM and KF5.COM. OO, Eric Don, is referred to as a “senior Internet researcher, systems architect, and Internet industry star”. He is also stated to be the CTO and senior partner of IT companies including YOULIN.COM, KITEME, and REINOT. However, it’s unclear if these websites actually exist as they did not show in a Google search or when entering the website domains. According to his LinkedIn, he is currently CTO at Youlin Network Technologies, yet there is no mention of KITEME or REINOT. With its growing user base and increasing number of cryptocurrencies being offered, KuCoin may be set up for a strong run in the markets. KuCoin Shares volume is expected to grow as the daily trading volume on KuCoin, hence, trading fees collection grows & thus, the size of dividend payout grows. This can lure investors to hold KCS token which may even increase its value. KuCoin faces stiff competition from OKEx, but it expects to continue to grow its community exponentially as it is being projected to be one among the top 5 exchanges in the world.
