PIVX sounds difficult to tell and remember. Definitely need a re-branding name.
Dash Unlimited
As in, 'not limited by a giant instamine, centralization, FOUNDATION, shitty pump/shill/troll cult community, etc.'
Oh wait, Dash is trademarked by a totally-not-centralized, totally legit and not at all shady Dash Foundation entity based in New Zealand and controlled by a Swiss shell company.
It would be fun to goad this decentralized-in-name-only entity into filing a claim, but PIVX may not want the hassle and association with Dash-style theft of another coin's name ('member poor Dashcoin?).
What about
Dcash? Short for "digital cash."
Since PIVX are confirmed and spendable ~instantly, while Dash's InstantSend has been broken/disabled since August, now is the perfect time to increase public awareness of that fundamental difference.
