DigiByte is no shitcoin at all. It has powerful fundamentals I think

Ok, too bad. You should try a clean install on another computer if you have the opportunity.
Test this fresh installed core wallet (opening, closing, let it sync until the end,  etc).
Close it and replace this new unused wallet.dat with a copy of your old wallet.dat.
Re launch, wait... and test. (All fine ? All your DGB are here ? after few hours: sync ok ?  etc)
Then you may also delete (core wallet closed) all the files and sub-directories existing in the roaming directory. Except the 2 files: peers.dat and the wallet.dat.
Relaunch and see if the core wallet resync from the beginning 'til the end (with your old wallet.dat).

At least you'll be sure there's nothing wrong with your wallet.dat, and that problems are in the first computer.
If all mentioned above works, then you could try to do the same in the first computer.
Always keep safely backups of your "old" wallet.dat

EDIT: By "old" i mean the latest working wallet.dat you've been using for your DGBs.

There has been a lot of talk over the past few weeks about the price decline.  I think that many people are using their individual short-term trading mistakes as a reason to suggest that there is a problem with DigiByte.
 
DigiByte has had a fantastic year.  Let's look at the facts:

Over the past 12 months, the DGB market cap has increased from $138,423 (at the beginning of 2015) to $912,837 (today).  That is a 559% increase in market cap over the past 12 months.

By way of comparison.  The BTC market cap has increased approximately 65% over the year.  LTC has had a good year; the market cap for LTC has increased 130% over the past 12 months.  Dash has had a pretty good year; the DASH market cap has gone from $8,398,731 to $14,801,837; that is a 76% increase. XMR (Monero) is up almost 90% in market cap for the year.  DOGE has had a hard year, they are down about 11% for the year.  Ripple is down about 55% in market cap for the past 12 months.  Etherium is down about 21% in market cap from mid-summer (release) to today.

We could keep going (I honestly got a bit bored doing the math for other coins) but the point is clear.  DGB's 559% increase in market cap is one of the most successful of the past 12 months.

Our exchange ratios are also up.  The liquidity (volume/price daily) is looking good and the average volumes are keeping pace with the increase in market cap.

Over the past 12 months DigiByte has released multiple wallets for Android.  DGB also released an iOS wallet (today that wallet is getting updated for version 4.0.3).  And, DGB released the chrome browser extension wallet.  

Over the past 12 months DigiByte has developed and introduced three major new services DigiByteTip (beta), DigiByte Gaming, and DigiByte Market.  All three of those services are still growing and developing and they will continue to get updated and developed over the next 12 months.

Over the past 12 months DigiByte also collaborated with TofuGear to release the omnichannel retail platform, which is a huge leap forward for bringing the internet-of-things into the retail environment.

And, in addition to all of the above, DigiByte developed and released DigiSpeed.  Some people have asked recently about why DigiSpeed was necessary.  I would answer that DigiSpeed is not about yesterday or today.  DigiSpeed is about tomorrow.  It provides the capacity to scale the DGB network in the future as the existing services grow and as we add and develop new services.

Over the past 12 months DGB has developed and released 5 new wallets (for mobile devices, browsers, and the core DGB-QT wallets), they have developed three significant new services that are proprietary to DigiByte, and collaborated on the omnichannel retailing platform, and developed, and released a hardfork to lay out the foundation for development and services in the coming year(s).

Read back over all of that ... it's not surprising at all that the DGB market cap has increased 559% during the same time.  DigiByte has significantly increased the underlying value of the services and network over the past 12 months.  

I would challenge anyone to give me an example of a digital currency that has accomplished the same amount in the past 12 months.

I don't really appreciate being compared to cancer.  I know Jared, and I can assume that he wouldn't like it either.  That's pretty rude on your part.  I've attempted to be polite with you over the past few weeks.  I've written about how we value your opinion and appreciate constructive criticism.  I do understand that you are upset because of the short-term price decline.  If you have constructive criticism or concerns, please always feel free to share them.

It's never any fun when we make mistakes.  I've lost a bunch of money in one of my retirement accounts this year.  Early in the year I decided to make a sizable investment in a small-cap stock.  It's only 1 of the 3 retirement accounts that I have - but I took about half the account and moved it into the stock.  And, it has just been hammered over the past 10 months.  I've lost a lot of money because of that decision (and I mean a lot of money).  But that's it.  I made a bad trading decision.  I bought at the wrong time.  I still believe the company has great potential, I just bought at the wrong time and lost money.  It was my fault.  I don't blame the company.  I don't blame the other traders.  I made a mistake.  I don't go online and write things about how the company is a terrible investment.  I don't go online and write that they are like cancer.

You can never succeed with trading until you take responsibility for your actions and decisions.  It's not DigiByte's responsibility to make you money in your short-term day trading.  It's certainly not the responsibility of other members in this discussion to make decisions for you.  We get it.  You made a mistake and bought DGB during the pump that happened in September and October.  You've lost money on the decision.  It's your mistake.  Live with it and stop blaming DigiByte and the DigiByte community.

a simple and awesome summary of DigiByte's Development for the past 12 months EPLDCC! a post like this once in a while is great to have to serve as a reminder to all of us, as well as providing a quick overall view of DigiByte's progress for the new people. 2015 alone has about 5 new developments. i wonder what 2016 will have in store for DigiByte!

i am okay if 2016 doesn't have anything new. But instead, bring all the 5 new developments from 2015 to Cryptocurrency 2.0 Level! In other words, tons of improvements, additional features & functions, image and design overhaul change with a more sleek professional look (tidier and neater too), massive marketing, etc.

buckle up everyone. 2016 is not a year for slackers and fudders! Time to get serious!

I think a lot of price speculation concerning DigiByte is purely a psychological thing.

NLG is a very good investment indeed and has a very deserving spot on my Top 10 list (and will likely move up on the year end report). DGB is still the undeniable #1 though.
