When the "Twitter Period" (5 LAT per tweet) is over, will the wallet still function?  Will you still earn interest on the LAT you hold?

Will you be able to earn interest on LAT (Ethereum), like you do with Classic LAT?  Will there be a new wallet for LAT (Ethereum)?  Will you be able to exchange LAT (Ethereum) for BTC or other crypto (on Enchanges) or is it locked in to just this proposed LAT eco-system?

When Ethereum switches to PoS, will LAT start earning interest, if not before then?
