Cool stuff, thanks for the heads-up!
So we get the incentivized testnet rewards until July 29 (before the hardfork) or we stop receiving them earlier?
No, the current ITN rewards are already depleted. (I think since 19th) But all the operators were asked to run the ITN infrastructure for at least another month to work out a plan/roadmap of what to do with the ITN going forward. The ITN is operated solely by the pool operators. They are the only ones in charge, the ones who can decide about it. Theoretically, this network could already now live on forever if the operators want it to. (without incentives of course)
