Burstcoin is definitively one of the more interesting altcoins. Apart from the "HD mining" feature, it has also some other features which people aren't talking much about:
- Crowdfunding: a simple mechanism to do a crowdfund in "Kickstarter" style - the "crowdfunder" receives the money only if a certain threshold is reached.
- Atomic Cross Chain trading: It provides a mechanism to trade coins with other blockchains without any centralized exchange as intermediary (the same thing Blocknet is promising). Unfortunately, for now, only Qora (an even smaller altcoin) supports that mechanism, but most other coins could implement it, too ...
These features are possible because Burst features a Turing complete smart contract language, like Ethereum. That people aren't talking so much about it is probably related that the programming language is not so easy to use like Ethereum's Solidity.
As for my review upon gathering information about Burstcoin, I learned that it is said to be the next generation crytocurrency (2.0) next to bitcoin.
Well that "2.0" thing was a recurrent marketing gag some years ago. It's
so 2014 ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)
