I love the idea behind Nano, but there's one issue that I'm trying to wrap my head around. Transferring Nano between Nano wallets is free, but exchanging it to other currencies like tether or USD costs money and needs to be done through exchanges like Binance or Coinbase. Since Nano is an unstable store of value, will there be some easy way to convert it into a stable currency? Otherwise, if I keep Nano to use as payment, the value of my holdings could double or halve overnight. Assuming I'm actually using it to pay for things I need, I wouldn't be able to trust its purchasing power.
It seems to me that if I want to buy something, the ideal way to do it would be to start with USD, change to Nano, make the transaction, and have it immediately turn back into USD or some other stable currency upon completion of the transaction.
