Regarding the NOXT not sold burning. It can either be given to and held in escrow by a trusted BTC or NXT third party, or left in the public 'chest'.
Or they could be burnt permanently by sending them to the genesis account:
NXT-MRCC-2YLS-8M54-3CMAJ.
Sure thing. I can do that. Will just mean if the cycle idea is a success then a new 'asset' and ID is issued in the future. I'm fine with that.
