2  Alternate cryptocurrencies / Altcoin Discussion / Gridcoin now trading for BTC and USD on www.C-CEX.com!! on: January 28, 2014, 10:14:59 PM
Just giving everyone a heads up that, as of this morning, Gridcoin is finally on its first legitimate working exchange, https://c-cex.com

It has a very a smooth and responsive interface, and from my experience instant deposits, trade executions, and withdrawals. If anyone is interested in buying or selling Gridcoin, feel free to give the exchange a try!

5  Alternate cryptocurrencies / Altcoin Discussion / CryptoKeep Portfolio Android App on: September 30, 2013, 01:38:38 AM
Hi guys, I decided to make myself a portfolio app for my phone using AppInventor. Anyways, I figured since there was no app for it I'd expand a bit on it and let others use it if they wanted to. It's in the Play Store as CryptoKeep.

I'm not a programmer by any means, and this is my first program, so I know it may not be very efficient and may have bugs so don't beat on me about it too much. Plus AppInventor has a lot of limitations compared to if I had time to learn Java and code it in that. If anyone finds any bugs, I can try to fix them when I have time between school and work. If enough people download/show interest in it I'll add more coins. As of now the coins in it are:

- Bitcoin
- Litecoin
- Feathercoin
- Worldcoin
- PPcoin
- Primecoin
- Digitalcoin
- Yacoin
- Namecoin
- Xencoin
- Solidcoin
- Novacoin
- Terracoin
- CryptogenicBullion
- Ixcoin
- Megacoin
- Mincoin
- Phenixcoin


Hope some of you guys find it useful!

10  Alternate cryptocurrencies / Altcoin Discussion / Concept for new coin on: April 13, 2013, 05:22:26 PM
These are just some ideas for a new coin, just to throw out for those who might be able to implement it or find it useful to build upon so don't bash me for they're implausible. I'm not a programmer and I've literally only had INTRO experience in programming, so I'm far from being knowledgeable enough to know what works and what doesn't. Anyways, this is what I've come up with.

How probable would it be to have a coin and a corresponding mining client that "hopped" between 3 or more algorithms based on a combination of random intervals and dramatic changes in hash rate (for example a 10% increase in hash rate within 5 minutes)? If the hash rate doesn't change within a time, it'll switch to another algorithm. If for an amount of time it still doesn't change much, then it will use those numbers for calculating difficulty. So difficulty would be what's calculated as average after any outliers due to ASICs jumping in during a compatible algorithm. This way, it would be a strong  defense against any ASICs and FPGAs. It would also keep GPU miners in existence for a much longer time. With this defense, a retarget time of a day or two would be nice as to keeping an accurate difficulty adjustment.

As for caps and lost coins, I think this might be an interesting solution should it be possible to implement. There should be some sort of verification or checking of client activity to see if the wallet has been accessed in a certain period of time, say a year or two. If not, a "virtual count" of the existing coins would subtract that amount from the count, which then affects the difficulty allowing more coins to be mined faster depending on how many "lost coins" there were. If for some reason, those lost coins were to come back into "existence" then it would take that into account and likewise increase the difficulty appropriately. The ideal "count" to work up to would be 160 million. I like the idea of the transaction fees getting destroyed, allow endless coins to be mined. If for some reason, a pile of lost coins were to come back and push the count over 160 million, 75% of the transaction fees would go to miners, and 25% would continue to be destroyed until the count was back to 160 million and then it would go back to destroying the entire transaction fee.

For the initial release, I think it would be good to have a retarget of a few hours for the first few days in order to keep the difficulty as accurate as possible to keep the first miners from getting a huge bulk of coins during what otherwise would be an extremely low difficulty for what would've been an entire day or two, in accordance to the original retarget time. Also, both a client and miner should be released for both linux and windows prior to the first mining day to keep it fair for all that want in. This include a guiminer for those who want or need it.

Again, I understand that some of my suggestions might not be possible, but these are just ideas, use them as you will if any of it seems worth anything. However, if anyone is able and does implement any of
my ideas into a new coin, please let me know as I would like to participate in a coin that I helped create. It'd be also nice if you would name it Xenocoin, as I think it's a really cool name :p
11  Other / Beginners & Help / Newbie Guide to An Open Mining Rig? on: March 16, 2013, 12:38:02 AM
Hi guys, I've been doing small time mining on different coins for only a few months on two desktops that I have. I figure it'd be a lot better to have a mining rack similar to the one in these images

http://imgur.com/a/E4y2q

Anyone have a small walkthrough on making one just so I know I'm putting it together the right way? I've tried to look for one online but all I can come up are tutorials for basically putting together a desktop or for rigs on sale.

Much appreciated,
Aysyr
