Sorry about what happened to you. This really hurts so much even for me to see someone loose their hard earned money.
I tried to do some small digging as to what may have led to you loosing all you coins and the fact is that BTC D wallet you download was the malware:
According to the wallet name you said you found in your download folder (Electrum-BCD-3.1.2-portable.exe). You definitely downloaded a Fake Electrum BCD wallet.
Genuine BCD wallet App - Electrum-BCD-3.0.5.3-Windows-X86-64-portable.exe
Fake/Hacker's BCD Wallet App - Electrum-BCD-3.1.2-portable.exe
It's now clear that you downloaded the app from the hacker's website; https://www.electrumdiamond.org/ instead of downloading from the official website of Bitcoin Diamond; https://www.bitcoindiamond.org/ [http://btcd.io]
Fake Bitcoin diamond's Certificate has even expired since 12/6/2018
I also noted that the Github user ElectrumBTCD from whom you downloaded the wallet file joined Github only 22 days ago and has only one repository. This is a complete redflag
Finally i decided to scan the said wallet on virus total;

My conclusion is this is the malware that got you funds stolen, whoever is behind it has your funds. Am not so technical in tracing people using ip addresses so i will just leave these here in hope that the info might help someone who is able to track back to the evil hacker or hackers.

"Bitcoin Diamond" was never safe. If altcoins and all forks in generals are scammy, well, "Bitcoin Diamond" was just a straight robbery. There were news about it:

It is also witnessed that there is no source code made available to the people, in any form of open source codes. As a direct consequence of which, the Trezor along with Ledger Nano S hardware wallets do not support Bitcoin Diamond. On its official website, one can also find murky wallets and they have mentioned it as Waltets.
There exists no blockchain or the source code and therefore we can certainly designate Bitcoin Diamond to be a fraud.

Well, this is insanity. No source code available and no blockchain? Anyway, I remember reading something fucked up about this fork and ignored it.
OP apparently also used the same password for password decryption as he used for online services? That's a no-no. And it seems you had a ton of money on exchanges too. Cmon guys, it's almost 2019. If you have 1 million bucks worth of crypto, put it 1 million bucks worth of effort into securing your coins, and remember to keep your coins in wallets within offline computers. Do not reuse passwords for online services. Pretty obvious stuff. Oh and try to avoid installing ANY altcoin software on the same computer you keep your bitcoins, and do not expose too much of your money outside of Bitcoin. Always check SHA-256 checksums if you are too lazy to compile source codes.
