X11 news!
I have spent time on analyzing Android wallet and API to exchanges, payment solutions and more.
At the moment new wallet with X11 would be most urgent to implement.

I am analyzing source code from Darkcoin, Megacoin and other coins.
X11 seems to be the correct choice now.
X11 seems pretty easy to implement. However we need to decide some details first.
The wallet could be updated to use Scrypt algorithm until block 50000 then it could start using X11 algorithm.

To be unique we could also introduce some unique touch like switching between algorithm un certain dates or even dynamically decided by developer at will controlled by a server without a need to update wallet.
Like on mothers day, christmas and new year we use Scrypt heating up your room and rest of the year X11 we are green and saving energy and that would be a reason to call it X12.
X12 = X11 + your mothers algorithm. Need to verify this is not causing problem because of different timezones.If too complex we start with fixed algorithm.

I also suggest to correct total coins to 50 billion as initially stated (a former developer mistake).
After some calculations in spreadsheet, this can be solved by increasing block reward for block 60000-80000 to 1500000 (1.5 million) then after block 80000 it will go back to 62500 block reward with normal block halving as before. This will benefit early miners again and is easy to understand.This next 20000 block range would be an insane mining competition :-).

There is no way we are going to introduce complex block reward algorithm like Darkcoin. Even if I am a very experienced developer it is really hard to understand the code what will be the block reward AND even worse to explain it to your grandmother.
It might be better mathematical solution but GrumpyCoin promotes simplicity and a fun currency for everyone.

Will have contact with exchanges and mining pools so we can decide date and calculate exact block start.

Questions:
1. X11 yes or no?
2. X12 or X11?
3. 20 billion or 50 billion?

Please give us feedback!

Stay tuned for updates!

Tomorrow big update day.

Looking at X11 how this can be included in Wallet.

Stay tuned for updates and next event! We will pump harder next time!

Thank you for the first donation!
Oops a little bug in webpage. Amount received is now showing correctly each 10 seconds.

thank you!

I am dumping some other remaining coins and can add some to the buy mania!
But little shaky after Cryptorush mess. Hope they will fix all their problems very soon. So bad for whole crypto world if another gox event would occur so soon again. Coinex.pw is down and coinmarket.io has "Please do not deposit any kind of coins." at their first page right now. Lots of red on coinmarketcap.com Whats going on?

When we finish payment solution, Android wallet and start upcoming events you will regret you dumped. The coin creator (not developer) abandoned but GrumpyCoin community is not abandoning. We just started.

I am working harder than before although you don't see it although some team members have been totally busy last two weeks. Creating new designed wallet  takes days or weeks not 5 min like other coins spend on cloning Litecoin.
This coin has done more serious development than most coin do. I think you are used to hurry with exchange so you can dump your coin. We promote buying GrumpyCoin not selling. This is not a speculation coin anymore. We will aim to convert this as a fun currency for everyone including using as payment in real world. It took several years to build Bitcoin community. Now you want everything in a week or two. Tough business. You also have to understand we just started after original developer left us in february with no documentation and no access to old account or sites.

Sunday will be big release day as mentioned with new wallet and websites updates. New ASIC protecting algorithm will probably also be implemented very soon but need more testing.

I have spend time also analyzing Android wallet and found a solution to be developed as soon as possible with live exchange info of coin balance. Payment solutions will also be developed.

Website is now updated with a donation page where you choose following donation types:

Block explorer webstats - we need to modify block explorer to have fancy webstats and show top holders.
Exchanges - in case we need to pay, we promote buying not selling, we are here to stay.
Games - coin games or other games, IOS, Android or IOS web apps
Giveaways - Need to collect coins again so we can create giveaways or events
Payment solutions - OsCommerce plugin or other popular shopping cart with direct payment with GrumpyCoin. Joining existing payment network
might cost.
Wallets - have some issues compiling OSX in 10.9 mavericks. Could be used for Android development or convert Hivewallet or other cool wallet.

After sending webpage will be automatically updated with your transaction from block explorer. We do developer stuff. Live Ajax, jQuery update of your transaction with heavy use stylesheet. No nerd grey layout in this coin permitted.

Donation is to speed up. I am sure as a developer I could take care of all development as I did with wallet, web app game, website layout etc but it takes much more time.

We have ideas for foundation and big events too. Not decided yet. So RIP GrumpyCoin? , RIP all fake coins. We are going to the moon with or without you mother.

thanks for your support

We are always looking at new technologies. We have talked about new algorithm to protect us from future ASICS and are looking at it.
There are lots of new algorithms popping up. Not sure if they provide anything new just because they say so. Most coins are created by non developers trying to claim to have a new unique coin using a new fancy algorithm name.
If you have good believable url not promoted by the algorithm creator please let us know!

Thanks for your support!

New wallet ready for test!

This is an upgrade to latest Litecoin and Bitcoin code using latest Megacoin wallet source as base with GrumpyCoin adjustment. Old GrumpyCoin wallet was really old based on Litecoin 0.6.x with a mix of BitCoin and some traces of SmartCoin created by old developer. This a big upgrade and cleanedup version. There is no trace of other coin in code like all other coins who clone Litecoin in 5 min. This is GrumpyCoin wallet with a unique design created by a real developer!

Features:
Wallet is using frameless window and can use round corners and other effects.
GrumpyCoin network parameters. RPC test port is 45998. Not in old source.
GrumpyCoin coin parameters.
GrumpyCoin difficulty calculation, not same as Megacoin, Litecoin or Bitcoin. This is GrumpyCoin KGW with one parameter changed as before.
Updated transaction fee logic.
Faster sync.
Leveldb new faster database.
Translations corrected with correct coin name and port names.
Removed hardcoded old DNS seed server. Using servers from grumpyconf.conf
IRC servers updated and is used to get more nodes.Can be replaced when permanent nodes are configured.
Filenames and variables has grumpycoin names, not Bitcoin,Litecoin or Megacoin.
Corrected layout bugs from Megacoin source.
Font changes.
Color mapping, rgb and hex codes.
GrumpyCoin images.
I2P network connection not supported anymore.
Includes icns file corrected format for OS X.
and much more...

Beta wallet will be given to our team first and will be tested with blockexplorer, mining pool and solo mining.
It is using new leveldb database to store blocks. Don't think that is a problem as other coins are using same database nowadays.
If you use wallet with old GrumpyCoin folder new wallet take care of automatic upgrade.
Dont forget a backup of your wallet.dat as always.
RGB chart shows what colors are mapped with black number to the right. Several colors kept because they fit our color scheme.

thanks,
and thanks for the info. Info on twitter, you already guessed the message :-).  I am lucky I withdrew my coins before.
I recommend to hold your GrumpyCoins or don't sell them cheap and if you are a big holder you are welcome to participate to improve your investment. We have a press kit at www.grumpyco.in/press-kit you can use and your webpage will be promoted to a lot of people on twitter and other sites.

Thanks for your support!

Payment ideas for the GrumpyCoin community!

(Taking a break before continuing with the new wallet. New wallet is going to be big!)

Where would you like to be able to use your GrumpyCoin?

There are FEW sites accepting alt coins that might be interesting. Most looks suspicious mentioned by big hype coins and several have no payment solutions at all, they are just lying and to be able to pay you need to contact them or do manual payments.
Listing below some interesting meaningful web stores accepting alt coins. Don't know if they work but good ideas to start with.

www.bitgild.com
www.revolutionarysupplies.com
www.securevpn.to
www.cryptodechange.com

Who wants to use GrumpyCoins to buy Bitcoin stickers? NERDS AND GEEKS and not your mother. We need real life stores where you can invest something you can touch with your hands or just buy something you really need. Flowers for your mother. New real wallet for your father. VPN is good to have if you want US Netflix or like to have access to geo locked webpages. You can sell anything creating a GrumpyCoin payment solution or join existing.

I think it would be interesting to create osCommerce plugin or other shopping cart software.Then we have thousands of websites to promote our plugin, 12800 sites according to http://www.oscommerce.com.
OsCommerce is included in lots of website starter pack for beginners like this http://www.byethost.com/paid-hosting/paidfantasticofeatures that also offers free hosting.

Bitpay has open source for OsCommerce plugin at https://github.com/bitpay/oscommerce-plugin.
Coinpayment.net is down at the moment. Have to wait to see if they will recover with new owner.

I have seen lots of new alt coins using long list on coin announcements.
They fill long links with url to newly created or unknown stores so they look active and big. I suggest to stay with quality only and not quantity and concentrate on few good partners.

List of payment providers alt coin or Bitcoin only.
www.coinpayments.net
www.moolah.io
www.bitpay.com
www.litepaid.com
www.coinbase.com/merchants

Would like to have some input from Android users also (check also with Kro55 at this forum). I am IOS, OS X and Windows user and the only way on IOS is to use Jailbroken device at the moment to install native payment solutions, however web app is good enough solution at the moment! Check out our web app FlappyGrumpy game its pure HTML but installable as icon in IOS.

If you find any more quality website please let us know in the community!

New wallet is now syncing. The problem was:
Grumpycoin is using Kimoto Gravity Well (KGW) with a parameter changed in the diff calculation. The error only occurred at  the blocks after the forking of the wallet the old developer did to implement KGW and when there was a big diff fluctuation the during the first blocks after implementation. The "." is now corrected.

Megacoin
1 + (0.7084 * pow((double(x)/double(144)), -1.228));
Grumpycoin
1 + (0.7084 * pow((double(x)/double(14.4)), -1.228));

I have found other coin using value 28.2 instead of 144.
If you are good at math please let me know what is the difference.
We will use same network,coin and diff calculation parameters as before to avoid forking coin at the moment.
Will do some tests now!

Stay tuned!

As soon as I see all blocks synced and basic functionality works.

I assume you have some basic knowledge in OS X, try to follow these instructions:

How to find your hidden Library folder:
http://support.apple.com/kb/PH11395

/Users/YOURUSERNAME/Library/Application Support/GrumpyCoin

Replace YOURUSERNAME with your name. Not sure about your name?
Click finder
shift+command+g
write
/Users
and go to folder,then check what is your name

Put your grumpycoin.conf file with content from http://www.grumpyco.in/faq/ in
/Users/YOURUSERNAME/Library/Application Support/GrumpyCoin
restart wallet.

More updates and satoshis coming up :-). Been busy this week with mostly new wallet. First version was mostly layout upgrade and next upgrade will be something cool with latest technology and I wont give up until we have the coolest wallet on the market!

Stay tuned for more grumpy news!

All other coins except this.
Thank you!
