that sounds like a great plan and a well thought out execution.

the only problem that i've seen with pure POS coins in general is that it is very difficult to move the chain while staking only.

many chains get stalled for weeks or longer because of this.

some dev's of hybrid coins continue to mine empty blocks after the pow phase is over the keep the chain moving but as you said, hybrid coins have a risk.

another possibility is to try to list the coin at POSWallet very prior to releasing the POS wallet publicly so that the group staking will keep the chain moving as well.

Thanks again for the update and sorry to hear about your troubles.
