The reason JPC price is so struggle is because that there were several hacking activities in Korean JackpotCoin community.
The first one was the big dump of almost 100M stolen coins a few days ago. This hacker stole not only JackPotCoin but also took almost USD $150,000 worth of DarkCoin, MaxCoin, DogeCoin, etc... This case has been officially reported to the Korean police department specialized in internet crimes. He can not speak English very well, so I posted about his loss here instead of him.
But this was not the end of story.
One day later, about 6-7 desktop wallets were hacked and about total 60M JPC loss were reported.
Fortunately the hacker confessed this activity, and sent coins back to the owners a day later. However he argued the first attack ($150,000) was not done by him.
It was a really movie-like drama.
During this drama, a lot of investors of JPC got so scared and thought it might be JackPotCoin's internal bug.
However it turned out it was not a JackPotCoin's bug. It was a misconfigured jackpotcoin.conf file and broken firewalls of hacked computers.
The hacker searched peer network nodes, and check the open RPC port.
Once he found the open port, he sent a RPC command to transfer coins.
So to prevent this kind of hacking, I suggest to disable the wallet's RPC server completely.
Most of normal users don't need this RPC api and it does not influence POS mining either.
Here is my suggested conf.
=====================
listen=1
daemon=1
logtimestamps=1
maxconnections=100
addnode=90.155.222.162
addnode=66.176.62.63
addnode=93.233.79.195
addnode=98.193.2.154
addnode=5.250.177.28
addnode=24.13.164.246
addnode=74.90.54.187
addnode=76.168.111.3
addnode=110.255.149.5
addnode=85.102.226.187
addnode=46.39.240.53
addnode=154.20.19.46
addnode=186.59.181.76
addnode=74.33.230.204
addnode=107.202.133.56
addnode=75.150.145.65
========================
After changing your conf file, restart your wallet.
Set up a password, and unlock your wallet.
After at least 24 hours (maybe it takes up to few weeks), your wallet will start mining.
Make sure your wallet works like this,
After this, you can confirm your RPC server does not work by typing this on your web browser,
http://127.0.0.1:15372You should see the connection failed like this image,
Now, your wallet is safe to any RPC attack even from your local computer.
However there may be a lot of different hacking methods, so you need to make sure your computer's security regularly.
One of the import things, check if your computer have any open ports to internet by using this sites.

===============
I think once our community regain the confidence on JackPotCoin's security, the price will go up very soon.
So it is another really good timing to get the cheap JPCs now.
