I assert that Nano is the best in terms of technology. It has no fees, is far more scalable than Blockchain based currencies, and thanks to its asynchronous architecture, transactions are fully confirmed in less than a second (under normal network conditions it's currently about 0.2 seconds). It's also more decentralised while currencies based on proof of work or staking tend to lead to centralisation of power. And it's green (no mining).
It does have some tradeoffs. Decentralisation depends on holders voting for a representative (so voter apethy might be an issue). There's also no data field for transactions, though this could be addressed with a second layer (the developers rightly wanted to keep blocks on the first layer as small as possible).
And nobody really knows about it. A bit like Hubski really.
But after actually using Nano to make a payment, no one would go back to using Bitcoin (or any cryptocurrency with fees and less-than-instant finality) for payments where Nano is an option.
Hubski is terrible for value transfer. :) IMO it's far too late in the game to compete with Ethereum. L2s are currently being implemented, and the developer and user network effects are enormous. Sure, Hubski could supplant Reddit, but I wouldn't bet on it.
It feels like you're reacting to something I didn't say. Did you hear me say "Nano will replace Bitcoin"? (I know non-autistic people hear a lot of things by implication even if they weren't intended, it's a constant hazard to communication but I won't hold it against you) Edit: I suppose I am hearing you say that if Nano cannot compete, then there's no point in using it. Which you didn't say. Perhaps I missed the meaning and purpose of your first point? Without implied meaning, your comment seems not to be really related to my post.
No. Nano could be useful well before it achieved replacing Bitcoin. But I don't expect even that to happen as Nano will need to be held by many to be best for the use case of value transfer. I don't see Nano reaching that level of adoption because of the alternatives that draw potential users for their network effects.
