hmm ya all get bored an wander off ?
dev said v1.6 is in the works so you all gonna wait until that rolls out then talk or what ?

I imagine most are too busy either celebrating cheap coins or shitting bricks about BTC dropping like flies to check this thread at the moment.

Me personally, nothing new. Mining all day and holding. I've decided that since I've recovered my fiat investments on JPC already, I'll let it all ride on the long game

I am solo mining. Not too worried because there is little to find on my single purpose (mining) rig. Wanted to share my experience as a cautionary tale for others.

I am behind a router. Access to my rig is blocked, except, and this is a big one, the plug-n-play had been turned on by (I think) a virus or exploit of some sort. So it's just another example of mining should probably be done on an isolated machine with separate wallets.

On a side note regarding security:

My mining rig is set up just to mine (Windows + JPC wallet + ccminer and not much else). I checked my router logs recently and found a lot of attacks. Some activity comes from University IT Departments, which routinely map open ports on the net. BUT most of the activity came from South Korea, Ukraine and here's the surprise: I had some attempted LAN access from 23.21.204.34:58679. Yep, miningpoolhub.com. Why would they be trying to access my ports? I hadn't visited them for weeks.

Miningpoolhub.com reverses back to CLOUDFLARE.Com a hosting provider a well known popular one too !
http://www.ip-address.org/tracer/ip-whois.php

If your running the wallet some guys may be trolling through the block chain sniffing for wallet IP address trying to connect.
I have not even looked and i don't care either.. let 'em their not getting in LOL
If your not solo mining pointed at your wallet then there should be no reason to have RPC access enabled (which is what their are prob looking for)

edit:
oh and are you behind a router ?

Hi, JackpotCoiners,

I will be very thankful to anyone for sharing the saved the performance comparison data on JHA algo from JackpotCoin Mining Hardware Comparison. The site is down for a while and there is no snapshot on waybackmachine.

Thank you

hey sorry i couldn't help you at all and good luck with that.

also have you guys noticed Bittrex has had the wallet down for maintenance it says ?
for a few days so far i noticed..

You are quite right about that some DB (old ones) don't scale very good when the block chain grows. Try starting a QQCoin or Velocitycoin wallet with big block chain, I think it would take 30-60 mins, lol.

Sorry to inform you but it looks like someone has hacked your accounts and performed enough fraudulent trades on it to drain the balance. We tried to stop the transactions and subsequent withdrawals but was unable to. I'm providing as much detail as I can in the hopes you can take legal action to recover your funds:

First it looks like your 2fa was on which allowed the attacker to log in:

Hey did i tell you guys i like Jackpot coin yet ? Cool

I think the Jackpot got won by the pool i'm on yesterday 10+ million coins
and i got about 1,100 coins on one of my payments from Dwarf rather than 110 coins
pretty sure it was because of the pot being won by that pool.

I'M RICH BIATCH !!! Grin

oh and i would spread my hash around on some smaller pools as the guy suggested earlier
but hey i am only mining between 400KH's and 800KH/s ..so who cares LOL
Guys doing 500 MH/s need to do their part and be responsible !

Introducing a JackpotCoin Slot Machine

It's not very easy to make provably fair online slot machine.
How can you believe that server side generated random number is true random?
Or, how can a client generate random number accepted by server eliminating a tiny possibility of hacking attempt?

I've come up with an idea.
1. No one can predict upcoming block hash.
2. Roll the slot. Server generates 4 random numbers between 0~15.
3. Wait for the next upcoming block hash.
4. Pick the last 4 digits of the block hash, which are supposed to be evenly distributed within the range of [0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f].
5. Compare how many of them are matching.
6. Luckily JackpotCoin block generation is average 20 seconds. Don't have to wait for too long.

Loock at the screenshot below.

Interested? Come and try. Coins On Table have added a new game, JackpotCoin Slot Machine!
https://cryptfun.com/cot/

Pay table
The full award starts from 2,000,000 JPC.
When any player inserts a coin, it will be accumulated into the machine.
4 matches will take 100% of accumulated coins in the machine you are playing.
3 matches will take 5% of accumulated coins in the machine you are playing.
2 matches will take 0.5% of accumulated coins in the machine you are playing.
1 matches will take 0.1% of accumulated coins in the machine you are playing.
Whenever the accumulated coins fall below 2,000,000 JPC, the system will refill it to 2,000,000 JPC.
10% game fee.

For some, this could be felt a bit too slow.
Blue machines are fast, more intuitive and fair, but it's not provable.

You can also enjoy player-vs-player rock paper scissors game.

This is really cool, the amount of thought and effort really shows. I'll give it a spin next time I have a chance to transfer some coins

Ohh fancy, Schmanchy, you got a new i7 Haswell now?! I'm just running it on an old Core 2 Duo 2.26 Ghz CPU, most other wallet works on it, so.
But yeah it is rather unstable when updating, but that is what wallets spends most of its time doing lol, at least mine. Tongue

yeah back in like November'ish i got that with Bitcoin profits

i had a Core 2 Duo hashing away but the PSU exploded while mining and i never got a new PSU for it so its a paper weight now.
i was pissed off too because i wanted a 6 core cpu but they didn't make them yet and about 2 months after i got mine Intel released them like they did on the last gen chips.

but the lagging and the UI saying not responding in the title screen i see when i don't run the wallets for while and then i try and do stuff with it..
but i never really have issues if i leave it running 24/7
i also noticed similar behavior on all wallets.. some worse than others of course.
like Max Coin has always been bad for that i recall.. when ever i loaded it up after having it off for a week it would lock up like crazy
and max out the cpu usage etc

i don't think any of these wallets scale very well at all.
the bigger the block chain and older the coin gets the worse they seem too.. that is my impression.
like right now i stake with JPC and it fluctuates between 2% and 5% on average total cpu usage on my i7 4770k with about 540mb reported mem usage (Private working set)
so that 5% usage would seem a lot higher on a crappy older CPU and that ram usage on an older system may be problematic..
imagine a machine running an older 1st gen core 2 duo with a slow clock rate on a badly bloated windows machine with only a gig or two of ram
then imagine the guy has a lot of crap running and uses the PC for day to day stuff.. you could end up with a wallet that seems to lag like crazy.
and i say 5% as in my wallet is ALREADY updated and idle (just staking) if it was updating from scratch it would max it out i am sure.

not trying to bash on JPC.. just saying all these windows QT wallets seem kind of similar with performance issues i think.
and if the dev is reading i hope the detailed info i posted is helpful Wink

@SolidStateSurvivor
hey yeah me too with the not responding thing occasionally.. Win7 x64 too

It makes it a bit harder to use the wallet, but I hope v1.6 will be free of that instability.

i should add that i noticed the issue when updating a lot of blocks mostly.. once it's updated i don't see that problem *much.
i also CPU mine and juggle how many threads i use making it lower or higher so i have some room left for other tasks on my Intel i7 4770k / Haswell 3900 mhz
So i am fairly sure i am not choking out the wallet is why i said that.. i monitor my CPU usage with a custom made OSD with Aida64's sensor panel.

I also noticed it's maybe more sluggish when i pulled out my fast new SSD Samsung evo 260gb and replaced it with another WD Black 1TB 7200rpm SATA
load times are crazy long now LOL
i was using a ramdisk for the wallet but i had a couple power outages in a week or two and my block chain files got corrupted bad and i had to re-download the whole thing
so i dumped the ramdisk concept for now but i've been thinking about setting it back up with Primo ramdisk.

anyway make sure you leave enough CPU computing power for the wallet to run and stake etc and i know most wallets use a lot when updating block chains
i see most spike up my cpu from idle to full 100% usage on all cores..

just some random thoughts LOL Wink

Had this problem from the beginning. I was writing about that, but nobody cared

It was freezing on Win Vista x64. But it ran normally on virtual XP 32bit... So I've used the wallet on virtual PC for some time. Now on Win8.1 x64 it freezes once in two weeks... Actually got only one situation when it crashed, then did not started and then started with lots of "not responding"... But now looks like works well again...
