At the current rate of 0.5 USD / XPM, I don't think that any (legitimate) VPS farm could ROI without speculating on a huge rise in USD/BTC price. Only "free CPU power" diverted from exploited machines could see profits from XPM today.

Anyway, we'll see if it leads either to a decrease in difficulty, or if the exchange rate goes back to 0.6+ in the following days. There is the current upward trend of USD/BTC, but currently besides hobbyists and a couple of fortunate hardware holders, I don't think this rate + diff is sustainable in the long run.

tl;dr: XPM is cool and hopefully here to stay, but not quite profitable to "mine" currently IMHO

you are right, let's hope the big dumping is done now...

Could anyone share an up-to-date addnode list?

Two nodes I'm running:

addnode=85.168.249.60
addnode=188.165.216.59

I have two others but they are already maxed out, 300/300 connections. The second one has a 1000 limit.

Raising the limit of incoming connections to 1000 may crash your node eventually. If you really want to do that, you need to increase the maximum number of open file descriptors first. This command will try to increase that to 2048 on Linux:

Code:

ulimit -n 2048

Now you can run "ulimit -n" to check that the new setting is taking effect. If it's not working, there may be a limit configured in /etc/security/limits.conf.

I did some more research into this and using "ulimit -n 2048" won't fix things. The problem is that glibc's select() implementation only support 1024 file descriptors. That's hard-coded into the system header files. There are some #undef and #define hacks around that but they don't seem to be safe. It's probably best to stay below 1000 connections. I'm running a node with maxconnections=750.

Does primecoin still produce a block per minute? Seems like less, though maybe that just because the computing power soo slanted towards those with huge server farms, botnets and 100s of VPS droplets

Ouch, what happened to the price?

The price is falling, come on guys please dont sell your hard mined with $0.5 each

I am hoping this leads to a decrease in difficulty. Got the last block 2 weeks back.

The pages on ppcoin.org and primecoin.org are coded by me and are very simple, I don't see any problem with the site right now. The avast warning might be flagged by the antivirus company due to known malwares bundling primecoin miners. Maybe we should drop them a note educating and requesting them to clear our name.
A quick search revealed that there are already malwares bundling primecoin miners, for example

Ah they almost hold you for responsible Sunny King... Fascinating to see how people jump to conclusion.
It was bound to happen, good thing AV will flag the miner to stop the botnets.

Wow there are a lot of people dumping xpm again this morning. I wonder if they are trying to get in on the bitcoin bump, just scared or bot netters. Personally I think it looks like a great time to buy.

I am not saying that the site is currently safe or not, but just something to keep in mind...

... a lot of programs that are found in the cryptocoin world are flagged by AV companies because the software (code) finds its way into (usually existing - 'plugged in') botnet software. When the victims report the infection or the box is investigated by the AV companies they just flag all the code as malicious and so it can result in false positives.

FWIW I am happy using primecoin HP releases and I have not come across any security concerns thus far.

You should all be taking basic steps to keep your coins safe anyway, like sending the majority of them to a wallet address you know is secured. Software wallet client(s) storing coins should be on boxes or at least VM's that you know are secure to a high degree...

whatever happened to primecoin? The price is crashing like pit. Undecided

The price has been trending down the last few days because bitcoin raised in value ~10 USD recently. The change to below 0.0050 BTC/XPM is because someone sold 20k XPM.

20,000?? When/where did that happen? I don't see where anyone even sold 1,000. But I'm just looking at Vircurex.

mcxNOW is the place you are looking for !

There has been several 1k+ dumps for several days in a row, one of those dump was around 18k xpm in an hour...

Now I a firm believer that the price will go up again, mining is a lot harder than it was and most of the people susceptible to dump have done so.
I'm still holding around 1.3k and I surely won't sell at this price !

Vircurex is a very small XPM exchanger. mcxnow is has orders of magnitude more trade volume.

+1

If you Virustotal cGminer, there are a ton of false positives.

AV companies really should do a better job filtering out those false positives; it gives crypto a bad name to unaware people.

I don't think they consider them to be false positives... Undecided
