Nano is today what Bitcoin intended and what it was created for. Bitcoin is now used more as a value store and not as a currency. While nano seems to be the decentralized currency of the future.
With Bitcoin the average transaction takes between 1 and 3 hours and has a commission of 20 dollars. The network is practically saturated at about 4 TPS (transactions per second). But that said, it consumes 0.3% of the world's total electricity production, which means that a single Bitcoin transaction consumes the same amount of electricity as a Tesla crossing the United States from New York to Los Angeles...
It is clear that Bitcoin is globally decentralized, but it is clear that it is neither perfect nor the best.
Nano has a fixed supply of 133 million, all in circulation.
No new Nanos are created.
NaNo could soon steal the prominence from Bitcoin.
If we look at its definition we will see that:
Nano is a commission-free, instantaneous, decentralized, scalable and energy efficient digital currency designed for large and small payments and value storage.
If we attend to your transaction speed we will say it is the fastest. It takes less than 1 second on average. In addition, with no cost you can make infinite transactions without losing your NaNo.
If we attend to your energy expenditure:
Nano consumes very little electricity, mainly because it does not depend on miners solving expensive PoW algorithms to secure the grid. To give you an idea, you can perform 6 million Nano transactions with the energy consumed by a single Bitcoin transaction.
By Scalability:
Theoretically it has no scalability limit, like other currencies, and could be divided into infinite parts.
If we attend to your commissions:
Nano has one blockchain per account that only the account owner can modify, and instead of relying on miners to secure the network, it uses an open-representative voting system. For this reason, commissions are saved for miners. What incentivizes node owners if Nano has no commissions?
Keeping a Nano node active costs less than $20 a month so many community users and many entrepreneurs mount nodes for the network to grow. This way:
Exchanges benefit from people who buy and sell Nano.
Sellers who save money for lack of commissions.
Investors who want Nano to be used and their investment to grow. .
Transactions with NaNo are irreversible. Nano has a deterministic purpose, which means that transactions are guaranteed to be irreversible once the recipient sees a weight of 51% of the votes of the representative nodes, which on average takes less than a second.

There are several Faucets to get some Nano and you can experiment with them in your exchanges, but perhaps the simplest and most cost-effective is the TipNano app for Android. I share a link for you to start, encourage and long live the Nano.
