RE: PARTICL = Bitcoin+Privacy+POS+COLD-STORAGE POS+Messenging+App framework+P2P Marketplace w/atomic swaps that pays dividends.
PARTICL, once known in a former life as SHADOW CASH,
Most of the Shadow team is working on Particl now, but Particl is a different project than ShadowCash, just to clarify. :)
Privacy is still at the team's core, in their products and a core value of Particl, but Particl isn't the SDC chain, has a better codebase (Bitcoin 0.15.1 vs 0.8), has better privacy (CT and RingCT vs Dual-Stealth addresses and ZK proofs.)
