To me it’s a very smart approach, indeed, if you don’t have fees all user would store their coin in the private wallet, hence Sybil attack would be much easier to perform.

I really see how to use it in daily life, I receive funds on my public wallet, they are public, but as long as it’s not possible to link me with these transaction it’s all good.

So basically on my mobile wallet I will have my public and private wallet, I can transfer immediately some funds from my public to my private wallet, and they become untraceable as nor the transaction nor the balance can be accessed right ?
And  let say I go buy a coffee, I use my private wallet to pay, I’ll pay a small fee, and in the end of the day I’ll get back fees depending of my balance on my public wallet ? Hence it means If I spend coin using my private wallet my fees will be paid back, if I don’t spend I’ll be remunerated to delegate my vote to a representative, to me it sound amazing as long as the fee is low.

It's like a freemium version of Nano, it's like XRB for public transaction, but if you want another feature it's possible but for a very small fee.

Hashgraph is just DAG. It used algorithm and consensus mechanism are different. Not open source, we can't really know what is done, it's all about hype and marketing for the moment.

Amazing project if it goes to the end it will be the best coin of 2018/2019, for once i'm at the early stage of a nice project, i'm very excited.

What would be the downside for you to have an higher supply ?

No you want a currency which is easy to use on daily basis, and of course you don't want to match the M2 supply but you don't want neither to have to pay for a coffee 0.000000000125 Azulik. People would be confused, it's much easier to pay 2 Azulik for example. It's just the human brain which is like that. On top of that newbie investor like cheap coin in nominal as they believe it double easier (which is silly we agree).

Yes indeed it's 666 millions i guess because it's 5 times the Nano (XRB) supply, and i read they wanted an higher supply.

Very nice the linearisation is pretty obvious on your picture.
Can you give us more details how you handle DPOS and privacy, i mean if i go there:

I can see that the first representative has 21 millions coins, and it should even be possible to check all the people who delegate to this representative and check their balance. If you hide balance how DPOS will work ?
