The existence of PTS does not hurt BTS. PTS is a DAC-agnostic implementation of the core DPOS Toolkit. It does not compete with BTS on features (how could it?) and it is not intended to "generate revenue" in the manner that BTS does. PTS will differ from BTS in the following ways:
* non-inflationary
* no application-specific features
* a jumping off point for 3rd party developers (extensible core DPOS Toolkit)
The anti-diversity crowd who wants to kill PTS is missing the point entirely. Very soon, 3rd party implementations of DPOS will become as common as Bitcoin clones. BTS is a feature-rich DAC with tons of advanced functionality (Pegged-assets, user assets, exchange, Vote, DNS, etc). 3rd party developers who intend to create a competing Vote DAC or a competing exchange DAC will never sharedrop to BTS (although an agnostic PTS would be a great choice). PTS will provide a hedge to investors who care about the Bitshares ecosystem to ensure that this community is vested in the protocol that we helped to fund, rather than just a single application of that protocol. We all hope that BTS succeeds, but the fact is that competition will exist whether we want it to or not. Why not vest yourself in the protocol by owning an agnostic, open-source, and non-competitive sharedrop instrument (PTS) as well as the killer app (BTS)?
