Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

GameCoin (GMC) is a digital currency targeted towards the gaming community. GMC tokens go on sale at the end of September through the GameCoin ICO. GameCoin aims to increase the revenue of the gaming industry by 3 times – or 300 billion dollars per year. It aims to allow players to earn money from their hobby. And, within a year, the developers claim the capitalization of GameCoin will “exceed and billion dollars and will continue to grow rapidly.” GameCoin is being proposed as a way to monetize the world of free gaming. The GameCoin whitepaper explains that the majority of gaming revenue comes from 10% of users. Today, developers are struggling to monetize the remaining 90% of users. GameCoin claims to have found a way to do that using blockchain technology. Basically, GameCoin’s idea is to allow each game developer to create their own cryptocurrency. This cryptocurrency is used as in-game money. The developers can create this cryptocurrency at virtually no cost to themselves – it’s just a digital token that has value in the game. However, by the time it circulates through gamers, the token will have value because it can be used to pay for in-game items. In more straightforward terms, GameCoin plans to make it easy for developers to create a secure in-game currency. It appears that these cryptocurrencies will operate as forks on the GameCoin blockchain. Each developer will be able to make their own fork – so gamers can easily apply their GWC tokens to any game of their choice (the GameCoin wallet will support all forks).
