NEO is often referred to as “Chinese Ethereum” or “Ethereum’s killer“ by many. I think many crypto projects have a great future because of their reasons for being built (i.e. the problems they solve). NEO is no exception.
NEO is the first decentralized, open-source cryptocurrency and blockchain platform launched in China.
NEO tags itself as a “distributed network for the smart economy”, and NEO’s goal speaks volumes about their smart economy concept.
NEO is a great project with potential equal to (possibly even greater than) Ethereum.
NEO runs on a specifically developed proof of stake consensus mechanism which is arguably the best proof of stake mechanism available. NEO’s blockchain is also quantum computer proof which gives it an upper hand in comparison to other blockchain projects.

ETH is one of the top cryptocurrencies. Ethereum is an open-source, public, blockchain-based, distributed, smart contract system.Many ICOs use Ethereum’s blockchain-based smart contracts to distribute and keep record of their tokens.
I think neo will be next eht when ICOs could use neo's blockchain based smart contracts.

Obviously BTC is better than gold because BTC is consider as digital currency as well as valuable asset. Day by day BTC value is increasing at a high rate but Gold value is all most constant so I like and interested to invest idle money in BTC.
