Cryptocurrency Chart

I ran across this handy little chart in the Bitcoin forum.

http://www.cryptocurrencychart.com/

The creator of the chart posted in the forum here:

https://bitcointalk.org/index.php?topic=364352.0

I'm not sure how I'll use it just yet but I keep playing with it and find it interesting.


Stablecoin

I've been looking for a coin that still feels like you can get in the ground floor. After looking through a few sites I ran across Stablecoin. It seems to have some good development support. As far as I can tell since the relaunch the dev team has been active and posting on various forum.



Right out the gate I had a problem. I installed the client and launched it then nothing happened. I couldn't sync to the network. I had created my c:\users\appdata\roaming\stablecoin\stablecoin.conf file as specified from the dev's post on a couple of forums.  No luck I was getting no peer connections.

After a few Google searches I found a couple of peer address that allowed me to connect to the network. I then went through my log file and skimmed off a few more peer address. It's late now so I'm not setting up any mining yet and I'm waiting for the wallet to sync anyway.

I'm not going to throw any hashes at something that as a forum user with the same sync problem I have put it "All the lights are on but no one is home". After the sync I'll let it stand and see if my connection to peers is stable before doing any mining.

For those interested in Stablecoin the stablecoin.conf file I used is:

rpcuser=username  <-change this
rpcpassword=password <- change this
server=1
daemon=1
addnode=108.186.237.29
addnode=188.126.8.14
addnode=84.170.27.129
addnode=109.197.195.116

Litecoin mining

I've been playing with Litecoin mining the last few days. Basic information about Litecoin can be found at https://litecoin.org/. I tried two different mining pools. Coinotron.com and Coinhuntr.com.

Coinotron I setup as a pay per share. They take a 3.5% cut and pay out minimum is 0.3 LTC. I mined with them and achieved just about 0.1 LTC per day with my HD7790 hashing between 220 and 250 kh/s. I also aimed a couple of slower Nvidia cards at the pool but their contribution was negligible.

I then gave my hand at Coinhuntr for a few days. It was giving me a little over 0.1 LTC but this may be attributed to some tweaks I made to my HD7790. Coinhuntr is a proportional reward system. Coinhuntr takes 1% fee and 1% donation so that would be cheaper in the long run.

Both sites seem to work equally well for my needs and I couldn't really recommend one over the other. One thing to remember about LTC is the required transaction fee built into the coin. As of this posting the fee has been dropped but it is best to cash out from the pool in larger chunks to avoid transfer fees later.

I'll put together a tutorial on LTC mining and post it soon.


RPOOL for Primecoin update

I have stopped mining on RPOOL. After 16 hours of mining I have not had a single share drop on my status page. I'm not sure if it is RPOOLs miner which I was using a modified version of the Beer pool miner or the way they issue rewards. I decided to go back to Beer pool to finish mining. Besides at 1% fee at Beer vs 2% at RPOOL I feel in the long run it is the better choice.

New Primecoin Pool

I knew about ypool and beer pool but I thought these were the only pools available. I just found out about rpool. It's a Chinese pool but the site has an English section.

What I like about rpool. It only takes 2% and pays out every .01 XPM straight to your wallet. As soon as I finish some pay outs on Beer I'm going to give it a try with the VPS machines. For those interested here is the link.

http://rpool.net/

You can use either ypool's jhPrimeminer or beer pool's primeminer. Here is the ussage:

Pool:    rpool.net:8336
Miner:   primeminer v0.6 RC2, thanks xolokram!
Usage: primeminer -pooluser=[payout-address] -poolpassword=0 -poolip=rpool.net -poolport=8336 -genproclimit=[threads-to-use]

Now you can use yPool's miner,T15 and T11.8 are tested, pool address is:rpool.net:10034
Usage: jhPrimeminer-T15.exe -o http://rpool.net:10034 -u [payout-address] -p x -m 31 -m2 37 -m3 41 -m4 47
                 Use the param '-t' to limit the threads you want to use.

Primecoin VPS update

It's the 4th day of XPM VPS mining for me using Beer pool. The first day started out promising. I was looking at possibly generating a coin every 2 days. Unfortunately the second day things slowed down and they don't appear to be getting better.

We may be looking at pool mining as the only real source of income for the regular Joe. If you had enough machines to throw at XPM you might do OK with solo mining in a private pool but I don't fall in that category. The thing I found funny is PrimesPerSecond (PPS) don't seem to matter as a stat that means anything.

There is a significant amount of luck involved in finding XPM. In a pool I do OK, I get my nibbles but solo mining on my i3 PC has proven fruitless. I'll let it keep running and hope for a chain but I'm not counting on it.

I'm considering converting it to a private pool and throwing a couple of core2duo at it for a week and see what happens but first I'll finish a full week of solo at minimum.

Not giving up on Prime just yet but it doesn't look as glamorous as I first thought.

ASIC Bitcoin Mining

I decided to give ASIC a try but as I've mentioned before I'm cheap. Not wanting to drop a load of cash on anything that has just one purpose I decided to try a Block Erupter.

You can find these on Ebay for about $50 to $60 USD. Far from a bargain. They perform better than a $90 ATI GPU but not by much and that's all they do. I've bee hashing at the advertised rate of 333 MH/s. They get pretty warm to so I'm thinking if I don't want to burn it out I need better cooling.

The advantage of the Block Erupter is that it pulls less power to operate and hashes faster than a GPU. The bad news is that 333 MH/s is not going to cut in the world of Butterfly Labs ASIC miners. BFL sells their smallest miner for $300 USD and it mines at 5 GH/s. Yes you would need 15 Block Erupters at even $50 each you have far exceeded the $300 mark. At $750 you could be hashing at 10gh/s with two BFL miners. The only thing the Block Erupter has going for it is you can get one now. The BFL and other ASIC miners are generally on back order until next year. Once they flood the market the Block Erupter will be as worthless as mining with your CPU now.

Still for me it was nice to get a little piece of Bitcoin history to add to me collection and I'll run the miner in the back ground since I have nothing better to do with it. Maybe in 10 years I'll have 0.1 Bitcoin.

By the way before you can mine in windows with the BE you need to download and install the drivers from this location:

http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Plug the BE into a USB port and it will fail install. Point the driver search to the download location and let it install.

After that I used Bitminter with it's Java GUI. It detected the BE right away as an Icarus on Com 7. I turned it on and 333 MH/s was rolling. The heat is outside of my laptop so I can let it mine and not worry about killing it. More than one laptop has been known to bite the dust on mining detail. They really aren't built for good heat dissipation.

I wouldn't say it's fun to play with a BE since there isn't much to it but it was an interesting 10 minutes to set it up. I don't think those 10 minutes were worth the $56 I paid for the BE though.

Maybe I can find another SHA256 coin to mine that doesn't have as huge a following yet has some potential. The might get a few more minutes of fun out of investment capital.
