A while ago, when the horrible Pi crypto currency project started, which used a local 'fountain' on a smartphone to 'mine', with one push of a button per day, I thought while not do something similar with a fountain on an offline computer and once you have some coins 'mined' you simply transfer the amount you like, as a file, securely to an online device and with that purchase then some online goods. If there would be a clever way worked out this would have IMHO the advantage that nobody knows how many funds I have in my offline wallet and the blockchain would only record the transactions. I think with the huge amount of different hashes, keys etc. a 256bit value, or greater can bear, there would most likely no collisions happen when many people create their tokens offline.
P.S. The fountain in Pi did not require that you must play some games etc. at some intervals per day, it only required you to push a button once per day.
The Pi project was or is still based on Stellar. Regarding Stellar crypto currency, keybase.io used long ago also Stellar and users there which had a wallet received monthly IIRC around 20-30 USD in Stellar, which I later exchanged to Euro. The project had an amount, I think it was 100 Million USD, which they give away for free in a certain time frame to it's users and it was quickly abused with thousands of new sign-ups at keybase.io ...
