Syncing and the system:

MangoCoinz is a centralized system and is comprised of two components, the miner app and the cloud system. The cloud system contains the blockchain, and the apps are there to mine the coin and to serve as wallets.
To be able to send your coins to other users you will first need to sync them with the central system. You do this by clicking on the sync button in the app.

There is a daily limit on how many coins you can sync, and that limit depends on the current difficulty present in the system that is equal for all miners. The limit will be proportionally lowered as the difficulty of mining the coin increases.

Syncing is light on mobile data use, and you dont need to sync a lot. It is advised to sync at least once a day.

But here is the good part. You can mine even offline.
Lets say that you go on a hiking trip over the weekend. You are in the mountains where there is no mobile data signal (this is rare today, but lets say that there is no signal), and you go on Friday. You hiked, mined, had a blast over the weekend and you gathered 37 coins. You got home on Monday and hit the sync button. You will be able to validate (sync) all of the 37 coins, and you will still have 3 coins left to sync that day.
Now how it works. The system remembers when you last synced. Lets say that it was Thursday before the trip. Now Friday, Saturday and Sunday have passed and allowed you to sync a max of 30 coins (3 * 10 MCZ) and plus you have the amount for Monday (3 * 10 + 10 MCZ). And with that max divided with the coins you wish to sync (37 MCZ) you are left with 3 more coins you can sync on Monday ((3 * 10 + 10) - 37 = 3 MCZ). But if you didnt sync those 3 coins on Monday the system will reset for tomorrow and you wont be able to stack those coins.
NOTE that this is just an example base on the current sync limit that is in the system which is 10 MCZ/day. At the time that you are reading this the daily limit might be lower.
EDIT We've made a slight change in the max number of days that can be synced. You can stack the sync a max of 5 days. After 5 days you will be able to sync a max of 42 MCZs (5 * 7 MCZ + 7 from that day that you are syncing). This is calculated with the current 7 MCZ/day sync limit, and might vary depending on the time that this is read.
Please note that if you, let's say mined 3 MCZs and haven't synced for 3 days you will be able to sync those 3 MCZs and you will have 4 MCZs left to sync that day. You have potentially a max of 28 MCZs to sync that day, but if you sync 7MCZs or more your limit will be reset to zero.

So, if you didnt sync for a whole day the system will remember and will allow you to sync an additional amount of coins equal to the number of days that you havent synced.

MangoCoinz is a centralized system because having a P2P network of phones, while feasible, is not practical. A P2P would eat up the users data plan and storing the blockchain on phones would also eat up their storage. And we cant expect that everyone has a flagship phone with an unlimited data plan and a lot of free storage.
And having users installing a node on their computer at home and having it run all day would also be absurd. And also with a small network of nodes there is a risk of the 51% attack where someone can setup a bunch of nodes and easily overpower the system and replace the legit blockchain with their modified one.

So to summarize, MangoCoinz is a centralized system because its running on mobile phones.
Its made to consume as little mobile data and phone resources (RAM, battery) as possible.
EDIT: The app is at 1% of battery usage, so it's not a battery drain.
To compare it with something, the phone's screen is at 40% of battery usage.
Maybe one day in the future when everything is stable and we have a large enough community willing to install nodes and to be extremely honest we will make a P2P network of nodes.

Is there any plan to re-increase the coinz mining daily cap? I walk a lot, 10 kilometers/day, and it's quite annoying to hit the cap everyday since I lost part of the mined mangocoinz.

Yes it might be quite annoying, but it would affect coins value in a negative way. Also what happend with service, i cant login it says that login is temporarily disabled Embarrassed

What is a reason behind this action? Huh
