Ethereum is a top cryptocurrency, second by market cap. Ethereum's low transaction fees when compared with Bitcoin makes it much user friendly. I have made several transactions with both for the purpose of comparing transaction fees. When I discovered that it cheaper to make transfers for trading with ethreum than with Bitcoin, I now decided to concentrate my transactions using ethereum. It has saved me a lot of costs. I think it is worth a try by crypto enthusiasts as a way of saving money while getting your transactions done as well.
Ethereum smart contracts is positive for the development of the crypto space.
Cons
Developers should endeavour to achieve a high level of scalability to enable a faster growth on the ethereum network.
