I think that some kind of warning should be placed in the description of the NEMstake asset (here: https://nxtblocks.info/#section/assets_exchange/stakeholders/12465186738101000735), so people know that it will be worth nothing in the near future unless they follow the procedure to redeem it for real NEM.
Maybe something like: "This asset will be worthless after XXXX date. The keep the value inherent to this asset, follow this instructions ASAP: [link to the phase 2 redemption stage]"
This way we can keep the number of unclaimed NEMstakes to a minimum.
I think that majority of the people is well aware of this. They are just waiting and trying to squeeze the most of the profits out of it by trading and they are also hoping for the big price increase in the last week.
Nevertheless it should be done, just so the people can't complain if they forget!!
You cannot change the description once it is written in there.
It is possible to send a message to every stakeholder.
Maybe from the issuer but the issuer is UP and as you probably noticed he isn't here very often these days
No need to be issuer to send messages to stakeholder NXT accounts. Everyone can send messages to everyone from personal NXT account.
I thought there was a function for an issuer to automatically message all holders if his asset.
You mean to manually send a message to all holder of NEMStake ?
Yes manually. There is 482 stakeholders as for now. But I do not insist of doing it Maybe few days before deadline, it will be not so much Nemstake owners left.
There is also possibility to send dividends automatically to shareholders. Possible to send 0.0000001 NXT as dividend with message in transaction.
