The tail emission avoids all this, the block reward never drops to zero and so the miners continue to be incentivized.
That pool is PROP I think, not PPLNS. That's the default for all those "node-cryptonote-pool" pools, unless explicitely noted otherwise.
No bad new driving the price down and now looks like Masari just got added on crex24. Time to accumulate more.
Sadly after this change we will loose ability to use free Claymore version. I hope that Masari devs will release custom xmr-stack without built in fees.
IMO, you'd be best to restore from seed. If you haven't already, note your seed within old wallet (command = seed)2. Close wallet3. Put v0. in a new location4. Open up CMD and go to the new cli directory5. Run: masari-wallet-cli --restore-deterministic-wallet6. Follow instructions and paste your seed when asked.
