Just knowing where the particular UTXO was spent or if the address was publicly posted as "his", nothing else.

I would be a game of cat and mouse.
For the hacker, he can just send the coins to a mixer or ConJoin to reduce the chance of being traced.
For the authorities (not Bitcoin developers), they use specialized software and tools to check if addresses belong to the same wallet or other techniques like Dust attack to accomplish it.

If you ask me, the hacker has the advantage on this game, but that depends on his wit.

That "earning through capcha" sounds like a faucet to me.

As far as I remember, Stake does have a built-in faucet with 100satoshi/claim if your account have 0 balance.
I don't know if you can claim more if you deposited to the site like other gambling sites did...
But the whole feature of the site is not that faucet.

Otherwise, stake is a legit gambling site; just make sure that you've visited the real URL (fake URLs through PM is a common scam).
Here's the official thread: link.

Check your browsing history if it's actually electrum.org or https://github.com/spesmilo/electrum/.
That's to know the reason why you've been hacked, but with this:

You won't be able to reverse the transaction.

For the validity of the address, read this: https://en.bitcoin.it/wiki/Address
(the 1st paragraph is enough).

Weird, one of my trust list must have distrusted ~ABitNut thus removed him in the DT2 list on my trust page.
I'm not seeing the negative rating.

But it's displayed if I set my trust list to default.

@StonerStanley It's not a major trust issue anyways, people usually refer to Trust flag for possible scammer profiles.

No.
And No.
You'll get what is stated in the "profit"; you bet 0.0001 for x2, you'll get +0.0001.

As everybody mentioned, it's all about the "House Edge", 1% maybe low at glance but in the long run (multiple consecutive bets),
you'll have a lower chance of winning (I even know one with 5% house edge).
Like 49.5% for a supposed to be 50% chance.
TL;DR: They earn through your loses.

Additionally, nobody have mentioned this: they gain additional income through withdrawal fees and other discreetly marketed promos that were designed to make you bet than hoard (who uses gambling sites as wallet anyways).
Notice that casinos usually have high minimum withdrawal amount but lower than the withdrawal fee minimum deposit amount? it's for ca-ching~.

That's why I said "feel" it's about "feeling lucky", it's maybe random but having a feature that I (or others) have accustomed to is a must-have for casinos with dice.

I have a feeling that it has something to do with the server's response to the gambler's internet connection speed.

I'm alternating between two ISPs depending on the website, whenever I try the slower one (my default for this type of sites),
I always encounter that 404 error during loading of either of the three casino games, or even loading the homepage.
But when I tried to use the faster ISP, I rarely get that error.
Both aren't connected to a VPN.

Hope this helps.

First, Technical Support isn't the right board for this kind of issues (this belongs to meta).

Secondly, AbBitNut isn't even in the DT2/DT1 list so there's no way that "that" old trust rating will show by default.
Next, Trust isn't moderated: Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ means that moderators will not meddle with trust issues (with some exceptions).
Lastly, check your Trust Settings if you've manually included him in your trust list or you might have selected Trust depth 3-4 and he's on that list.
If you did, set it back to default = 2.

The input's balance isn't relative to the size.
Whether a UTXO is 1BTC or 10,000sat, the size is almost the same (the difference will be too minimal to notice).
The number of inputs/outputs dictate the size.

Using the instruction above,
I suggest you to sort them by amount and make another transaction using the smaller inputs using a very small fee like 1sat/byte (consolidate).
If you're in a hurry and need to use high fee, spend from the high balanced ones and as much as possible, select fewer than 5 inputs for high fee transactions.

Check the total fee in your 2nd image  

That particular transaction is 10.9kB larger than the default maximum allowed transaction size which is 100,000 bytes.
There must be a lot of inputs included and the server you've connected to had rejected your transaction.

I guess you're sending all of your wallet's balance....?
But anyhow, try to remove some of the low-value inputs by displaying the Coins tab (View->Show Coins),
then freeze (right_click->freeze) the one's with very low amount to exclude them to your transaction.

Alternatively, you can select which inputs to spend from using CTRL+Left click to select (highlight) your preferred inputs then Right click->Spend.
Then the send tab will be displayed with those inputs already included.

The file name format resembles this description: (so there's a high chance that it is a Multibit classic wallet)

With your reply, I guess you've downloaded the "classic" not the HD version and successfully selected the file, right?
then that "word" must be your passphrase.

If not, download the Multibit Classic instead of Multibit HD and use "File / Open wallet" and browse t the location of your wallet file(s).

You should at least provide some evidence like a quote from those email and purchase screenshot/vouchers, etc.
Then make an official scam accusation (as much as possible) in complete detail on this board: Scam Accusations.

This will likely get nowhere like the ones I've seen in other Marketplace threads.

It's a backup thinggy.
If you still haven't clicked "Post" or "Preview", and the browser crashed/PC shut down unexpectedly, there will be no draft for that particular post.
Drafts will be saved after you've clicked either of the two buttons.

If you click "preview" once, there will be an immediate backup of the current version of your post (good as backup).
And another backup of the final version after clicking "post".

You need to specify the address when you call "sendtoaddress" like: bitcoin-cli sendtoaddress "other bitcoin address" 2.1 (including the quotation marks)
"getnewaddress" doesn't automatically select the one generated as the next receiving address.

Next, I just tested Electrum, it also indicates any self-send transaction with "0 amount sent" like BitcoinCore does.
Even sending to a different address from the same wallet.

I was gonna say "mine altcoins" then I saw this

@WLtoys V912
Mining is a good choice for that "$1 a day" earnings (literally) as long as you have free electricity (or paid by your parents); have a decent GPU and CPU. That "free electricity" alone will obviously grant you more than $1 a day.

I'll just leave you an advice to research the basics very well for you to not fall for "gimmicks" that will cut your profit under the hood like minergate and "others" that offer the same gimmicky service.

By the way, "0x18160ddd" is the signature of the function totalsupply().
but I can't tell why the value wasn't there.

I think you mistook "Ethereum" for "Electrum" :)

This isn't the right board for technical discussion about ETH.
Use the move topic button below (lower-left) to move this to Altcoin Discussion.

not "-allpools", -allcoins 0, or try -allcoins exp:

The thing is, you've mentioned "you have to use a file from GitHub" and that's the first thing that I remember (&it was, I guess)
That's why the example was about using that mnemonic generation tool.

Additionally, Electrum doesn't guarantee that "BIP39 support" and it might be depreciated in the future,
If that happened, you can still use your BIP39 Mnemonic in other tools/clients that support BIP39;
something you cannot do with set of random words that has an invalid checksum.
(though you can download the older version that still support it)

You mean this: https://iancoleman.io/bip39/?
It quite easy really, all they need to provide is the BIP39 Mnemonic Phrase from that link/code and select "BIP39" in the option below the "I already have a SEED" input box.
After that Electrum will provide options for the user if he want any of the three address types of a standard wallet (not available for old versions).
Pretty same difficulty as creating a standard wallet.

The only "sensitive" part is the part when the user create the BIP39 SEED (S...E..E...D....  ).
Not rocket science, but a security risk if not done right.

No one mentioned that it's already confirmed... yes it was.
If blockexplorers like blockchain.com doesn't show "x confirmations" or "unconfirmed", it already have hundreds of confirmations.

Additionally, it got the first confirmation in just 2 hours after you broadcast it, so it should be your Ledger live app.
