Even better than earning interest is the Bitshares social consensus: just for holding Bitshares PTS you get an at least 10% sharedrop in all future Bitshares DACs (decentralized autonomous companies). PTS just hard forked to use Delegated Proof of Stake (https://bitcointalk.org/index.php?topic=878059.0), which means that in addition to being the original sharedrop instrument, PTS is the first DPoS coin with 100% PoW distribution, no premine, and no inflation. Coinmarketcap will be updated shortly. Poloniex has resumed trading on the new chain and Bter will transition and resume trading soon.
