Here's why I think antshares is a good longterm investment:
Ethereum is the king of smart contracts. Major updates are coming to the network. Metropolis/Raiden, ZN-sharks, Sharding, Payment Channels, Casper, etc. are all coming down the pipeline. It has the best development team in the crypto world and will outcompete many of the existing alt-coins as they are just less-powerful and less-secure redundancies of Ethereum.
Hear's the thing, the Chinese don't give a shit!
Look at every dominant network technology that has emerged out of the West and the Chinese have their own (arguably less technically advanced) version.
Chinese Facebook: Renren
Chinese Messenger: WeChat
Chinese Google: Baidu
and I believe Chinese Ethereum: Antshares.
