Yes lets call 0.0001 mcz 1 srele

If we are not very obsessive of always having to call every things here Mangocoin~ or MCZ~, start using "Srele" (or any terms to that effect) as the only major denomination for mangocoinz rewards, transactions, and balances would be the least confusing ways of achieving what we may want.
In this case, the display would be
Total: xx,xxx Sreles https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRVRbdw33ODk7VrwaugLmgBEZZqQpWtXa-kZHyMR7R-krVq4UhtTw Click for Balance in MCZ Now, you would start to be rewarded 1-530 Sreles (i.e., 0.0001-0.0530 MCZ) per minute mining Mangocoinz, you would get up to 60,000 or more Sreles per day.
There were plenty of cryptos starting block rewards of 10,000 or more.
For exchange(s), they would just need to be told to trade in Srele denomination. People, including those trading at the exchange(s) in china would be immediately excited?

As to speculation of Mangocoinz on the markets,
with or without any change in Mangocoinz denominations, the
values, uses and prices of Mangocoinz would rise up very soon and steadily unlike other cryptos where miners are usually not necessarily users, traders or "bagholders."

I am favoring the change to either
new MCZ vs old MCZ or
Srele (=0.0001 MCZ) vs MCZ.
The reasons are not prices although you would expect to have at least short-term (& usually confusing effects) in helping prices to rise, not unusually seen in trading of equities or commodities when splits happen.
The Mangocoinz has yet to solve some of bugs for Android phones and Apple store Mangocoinz App has been anticipated to be released soon.
The price will not rise much until the time is right but Unless the iphone Mangocoinz users respond better (, " I think")and I have not seen any fast propagating effects in Android phone user bases, any supporting trading activities would be futile and short-lived just like most cryptos.
I only trade at the BANX.io where only sells of less than 300 MCZ per order are listed; not much for me to buy up. Feel free to come to put large sell orders here.

"I am favoring the change to either new MCZ vs old MCZ or Srele (=0.0001 MCZ) vs MCZ."
The former,new MCZ vs old MCZ,is better than the other one.
I actualy like srele over old and new mcz, old and new mcz can be confusing and unclear to new users...
