Hello, thank you for your interest and welcome to the thread for the new comers.

First i will answer about the fees, they will stay fixed at 0.2%, which is a competitive rate compared to the most famous centralized exchanges like pointed by aubert, these exchanges fees are at 0.25%. I want to point also that these fees are lower compared to bank systems.
Why am i giving this example ? NVO will redefine the bank system.

The difference between Exodus, Jaxx and NVO is that NVO's plugin system will let cryptocurrencies developers to provide support for their coin into the NVO wallet. In the case of Jaxx and Exodus, it is up to their teams to add support for coins while in NVO it depends of the cryptocurrencies developers Which makes NVO's coin support decentralized simply because there will be no more looking for the top 10 currencies in marketcap to know what to add.

It is true that NVO will use this method at its launch but will deliver at the same time its plugin system.

Example:
Harry Potter decides to create a blockchain in the wizarding world to avoid tax evasion that would restore voldemor once again.
He will have his community but he will not be able to post in bitcointalk as he will be in the wizarding world.
There is no exchange there, but he would be able to download the wallet NVO and to publish his currency into the wallet, which will bring more volume, it will be up to him to promote his currency without NVO's intervention.

Why NVO will redefine the banking system, let's check this link: https://www.uber.com it is a huge transport company which offers a decentralized service from particular to particular, when you register on the site they will Ask for your credit card, which reduces the vision field of decentralization. NVO will be a possible solution to this problem if UBER decides to use payments in crypto currencies, it is sufficient to integrate a plugin UBER which will allow a user to pay for this service via exchange by the Validator, the cab will receive Its payment by UBER, and UBER will receive its payment by the Validator, which guarantees the security of the exchange, and therefore of the service. Either the Customer sends the money to the taxi, NVO takes a fee, and UBER takes a fee if both customer and cab accepts crypto currencies, and in case the taxi does not accept crypto currencies, the customer will send cryptos to UBER then UBER will send fiat to the taxi.
Hence the revolutionary payment processor system. I could give you lots of examples, that's why i said NVO is a revolutionary Wallet, Exchange, with advanced features, this project cannot be compared to others as NVO team offers large bridging capacities.
