SPR is dead,it's time to go back to invest in DRK

ZiftrCOIN had a good anti-pool strategy too ;-) (at least for the launch)
ZiftrCOIN wallet is similar with spr.

Maybe it was just a beta-test for ziftr
Each ziftrCOIN is essentially like a decentralized, digitally issued coupon redeemable on the ziftr merchant network for a guaranteed minimum of $1! In 2015
The last time I heard someone say 'guaranteed minimum' value was XPY which said it would guarantee each one would be worth $20. People pumped loads of money into that, and puff. Its all gone.
Ziftr sounds scammy.
