I have never heard of most examples of what you wrote. Now you could say that, that just shows my ignorance, and I suppose that is somewhat true. After a while I just wrote off cryptocurrency's, as a waste of my time. But on the other hand I have never seen any of those cryptos as an option to buy anything I ever wanted to buy, and I buy most of my stuff over internet. I have also Implemented checkouts for various online stores and have been asked several times to implement bitcoin support. Never been asked for any of the above coins. After brief googling for Nano as you gave it as example, I mostly found how you could buy the coin or exchange the coin for some other coin on various exchanges. I am sure if I would spend more time, I could find something somewhere to buy that is not crypto related, but I have already spent too much time on this. As far as I am concerned my point still stands. Except for bitcoin and Ethereum, there is little you can buy with any other cryptos. And if you can't buy stuff with it, it's not really useful as a currency in my not so humble opinion.
