NXT is amazing, but it is undervalued because every good cryptocurrency is currently undervalued. We are currently in a brutal bear market that is testing every coin and every community with fire. Only the strong will survive. Only the full feature, true 2.0 coins will emerge at the other end. By the time this is all over, the value will have shifted from 1.0 altcoins that are nothing but glorified Bitcoin clones, like Litecoin and the hundreds of other copy alts, into the few true 2.0 coins which have their own codebases, which have assets and voting and scripting and other features.
First everything is going down, and then only the cream will rise back up.
So to sum up class, NXT and BTS are basically a decentralized Ripple with different advantages, NXT is more decentralized and is focused on beating out XCP, Open Bazzar, eBay, and Craigs list.
You can’t sell your bike on BitShares, but because BitShares has Ripple fast trading transactions, you can trade commodities like gold, silver, bitcoin, USD, Yuan, etc.
Excellent summary, and this shows why it is important to own some of both.
