Note that I have submitted changes to them before but I haven't seen my suggestions go live.  While they may not support data from all of the exchanges we are listed at, I have noticed that Nova was listed on another coin on their site while we have yet to see Nova listed.

I deposited funds at BtcPop to test their on exchange minting/staking.  After only one day I received a distribution for coins held.  Not bad.  This isn't an endorsement of BtcPop.co but rather a verification of functionality.  Minted coins show up at btcpop.co/Alt-Statement

This could be a solution for users who want to stake but are unable to run their own wallet.  Keep in mind, you will need to trust BtcPop while your coins are in their possession.

Stay minty fresh my friends.  

Work continues in the background on the mint wallet along with other mint projects.  While I'd also like development to move faster, I understand that we are a community based coin run by volunteers.  Translations are always welcome but there is not a budget in place for such projects.  Google translate is a more cost effective solution then paid translations.
While I'd love to discuss projects we have planned in more detail, the current team has agreed that we don't do pre-announcements.  Such discussions can facilitate speculation and unreasonable expectations.
We don't have ICO or pre-mine money.  We don't have corporate backing or a hype machine.  But we do have a lightning fast, working coin, with a friendly atmosphere of transparency that anyone can participate in.  

I'm sending a few other emails out to services regarding info and updates etc.  I'll add Bter to my list for this weekend. 

At almost 3 years strong, mintcoin's quick 30 second block times allow for speedy transactions.  POS allows for energy and cost savings as opposed to POW.  

The friendly and inviting mint community maintain the coin without IPO funds, crowd sales, or expectations of profit.  
Mintcoin has a tradition of charitable giving to earth friendly charities.  While there is not a particular campaign running at the moment, we expect launch a new campaign in the future which sets new levels of transparency in charitable giving.  

The mintcoin team has progressed thru multiple devs and 3 phases of community leaders and has continued to flourish despite multiple re-structures.  The team is transparent and available.  Anyone is welcome to join and contribute.  Be minty fresh.  

Minting happens when you already have the full blockchain downloaded, your wallet is unlocked (for minting only), and you leave it running.  Coins mature after 20 days and are ready to mint but compete with other users on the network.  Coin age and weight are important factors in minting.  You'll see newly minted transactions come into your wallet which take 50 confirmations to solidify.  Generally, if you don't want to mess with the wallet much but you want to stake, you can open your wallet once a month to download the blockchain and earn rewards.  Minting is not required but how else will you STAY FRESH.  

[EDIT] Forgot to mention orphans.  If you see minted transactions come in which turn to question marks it just means that another user on the network was "ahead of you in the line".  In these cases you can either let your wallet run and ride it out, or try minting another time when there isn't so much competition on the network.

You may want to consider that the act of minting actually involves leaving your wallet open on the network for rewards.  You wouldn't stake with litecoin or doge so it would be unlikely you would leave your wallet running once the full blockchain is downloaded.  Step away from the running wallet, enjoy some fresh air or some mint flavored gum, return to minted coins. 

Your buying mint at btcpop.co?  How long have you used them?  I'm having issues logging in there to even see the coins on their exchange.  I've sent a support message to them.

The wallet redesign has the new logo and uses new minty colors.  Old links are stripped out and or updated.  I THINK I've shared preview images in the past but I don't recall currently.  I'll need to clear any public sharing with some other team members this weekend though.  But while this preview looks cool, it likely won't be the final design as we still have time to tweak things while working on the new code.  I don't believe the new wallet will require a new blockchain download but if it does, it should be improved in regards to loading time.

Devs should be more active online next week.  New wallet design happened quite sometime ago.  However, we're bringing the new code up to speed before releasing the new design.  But if your hoping to contribute in some manner, we can always use more team members. 

AltEx responded to my Twitter DM with their bitcointalk thread URL which shows that they are making some updates and should be functional later today.

https://bitcointalk.org/index.php?topic=1590781.0

Just sent them a DM on Twitter for more info.

I am still engaging them thru Twitter to try and find a reasonable path forward before listing the exchange on mintymintcoin.com.

I've been told that this message was posted after the hack which occurred on May 4th, 2016:

novaexchange.com/message

When the site re-launched on June 4th, 2016, an additional message was posted:

novaexchange.com/notice

Coins are still owed to users and there should be no reason that they cannot be dealt with directly and in a timely manner.

Another important link may show a level of accountability:

Thanks for your post jacee. 

I've received a response from Nova in regards to the confusion surrounding their exchange and the creation of this thread. 

I've asked them to allow me to post that response here in op or post their own response within this thread.

Mintcoin was recently added to Nova Exchange.  After seeing their official thread (https://bitcointalk.org/index.php?topic=1440340.0) I am a bit concerned about previous customer interactions.  Unfortunately it appears that the official thread is locked(?) so I'm starting a new community thread to try and understand the current Nova Exchange situation.  Are you owed funds?  Are you able to clarify a history of events in objective terms?  I'm interested in hearing from you.  Post your experiences here and let's get the discussion started. 

So true.  During their times, they were top volume exchanges.  Mint is invasive and just migrates elsewhere.  I FEEL SO FRESH TODAY.   

Do you have a direct link to the btcpop.co exchange or even a list of the coins they offer?  I was unable to find access to the actual exchange or their coin list on the site.

We're working to understand the issue so we can potentially reverse any removal.  We'll be working on this throughout the day.

Oops, sry.  Mis-read.  Do the figures at coinmarketcap or coincap.io work for you?

Please email me at mintyallday@gmail.com and we can work thru the details for the domain transfer.  Thanks cryptomommy.
