Seriously, you really need a front-end developer in your team.
Or at least pick a less-stressful color, gamblers will stare at their monitor for hours and the visuals are pretty important in that case.

My question is:
If ever a gambler questions the coinflip's match making for being suspicious about his previous opponents, claiming that those must be bots, what would be your answer?
And how can you explain to us that it is a "real" player, not a bot? Because it's technically possible.

Are you sure that you've used the correct address from your Electrum wallet?
If the transaction from your "Blockchain Wallet" does went fine, there should be a received transaction in the history tab on Electrum.

It could be:

• The first transaction is still unconfirmed; if it is, just wait a little bit more before sending from Electrum to Bitpay.
• Your Electrum wallet isn't synced and still haven't "notified" of an incoming balance.
  Look at the lower-right circle on Electrum, if it is Green it's synced; if Red, you're offline or disconnected.
• Is that "blockchain wallet" an online wallet? Because most newbies mistakenly identifies Bitcoin from Bitcoin Cash and most online wallets supports both currencies.
• Your Bitpay card obviously didn't received anything since Electrum must've not received Bitcoins at all.
• Lastly, can you show us the Tx ID of the first transaction (any link from a blockexplorer is fine) so we can tell the possible problems and solutions.

Assuming that you copied the correct address, the money isn't lost.

Honestly, it will be tough to startup something like a learning portal through ICO.

First, and obviously because most of the competitors offer free basic services.
Secondly, ICOs are best used as an asset or share-based unit, not as the currency for transactions and payments.
Lastly, People online aren't interested on being taught to learn at all (yes, that's the truth), mostly looking for information for a couple of things like hobby, curiosity, get rich quick, etc.

Here's my suggestion: You will find it hard to find the potential investors if you just offer the said service as it is, you need to find a unique additional service along with the learning portal if you want this to succeed. And that's the million-dollar assignment for you and your team.

Regards.

You can't use the official Electrum to Bitcoin Cash. Use TryNinja's link.
Either no or Yes, they are easily distinguishable: Bitcoin is BTC, BitcoinCash is BCH;

Bitcoin isn't classic, it is still the official chain (perhaps, Roger Ver has used the term "fork" in his scam)
selection of the official chain is "voted" by the nodes and BCash's chain has just been "kept alive" by their supporters,
I don't want to turn this into a debate so, there you go.

Is this based from your reply from the thread: Public permissioned blockchain?
Because I still haven't found a post of yours that stated something like:
Because the OP of that thread didn't presented a Public permissioned blockchain but asked the technicalities about it.

I don't want to be a bummer but, the title itself (without PoW) spells a lot of potential vulnerabilities and I won't make a long list 'coz it's a pain in the ass.
Here's a shortcut:

• [1] Is this supposed to be in the list?
• [2] Why would any coin developer do that?
• [7] Transactions aren't Board/Chat rooms.

And the list... seems like you didn't understand the term "Blockchain" at all.
No worries, it's pretty normal for a newbie.

Here's a refresher: https://en.wikipedia.org/wiki/Blockchain

There's no clear user interface or guidelines, so it's quite not user-friendly. Not for me, at least.

These might help the visitors:

• If the box is light blue (which is a link as default in HTML pages), it is clickable and expandable.
• To Zoom out, click the top row (current position/location) which highlights in orange when properly hovered by the mouse pointer.
  Because sometimes, it seems like not responding to clicks.
• I works with a javascript and some users set their browser's javascript disabled, some may report issues.

Overall, it's useful for merit source/huge merit trading search.

Can you add a space where the small merit senders are listed?

I mean, when you buy bitcoins (from an exchange in this case) in some cases you don't have an option to choose the tx fee of the withdrawal request.
If this was from December, when you directly use the invoice deposit address from the mixer (Buy Bitcoins -> Send to Mixer -> Your Wallet) and it didn't make it in time, that's the risk (for a newbie like OP).
But as I said It may never happen again after the recent updates, so, it's not much of a subject for discussion.

Oh my god, we should panic!

The price just got pumped up by 3%! expect it to drop by 5% after the dump.
This is one hell of a price manipulation by the Whales, there's no way that this is normal. [/sarcasm]

After the first few replies, I can't seem to understand why someone still take the time to type with that kind of reply, you just simply whispered out "Nuke my posts please".

By the way, I didn't see where OP stated the $2b approximate for the lame "pump report".
-edit-
Saw it:

Good shortcut, except the risky part during times when unconfirmed transactions are clogging the network and normal transaction could take more than a week.
Today, it's risk free even for a newbie.

There is really no point here unless you're strictly conscious about your transaction and asset's privacy not against the regular users but the "Big Guys".
Otherwise, someone like me won't be able to tell if those bitcoins from an address belongs to you (unless if motivated/payed to do so).

Bitcoin was designed not to be anonymous,
But not re-using an address can help you keep your privacy safe, do not disable "Use Change Address" either.

If you wanted to be "slightly" anonymous, do the mini-mixing yourself by utilizing all of the addresses in another Electrum wallet.
Or just use a mixer service to skip the hassle.

Yup, by brute-forcing the key, the chance to hit a collision is close to 0.0000000000000000000000000000001%. Wait,

No, what they talking about (in this thread) are those neglectfully stored wallet.dat files, private key backups, paper wallet images or other forms of backups which potentially have funds.
History can tell that some people are stupid enough to store those (not only wallets but passwords and sensitive info too) directly in the internet without "hiding" the files with a disguised file name, file type, etc.

This one for example:

@OP, this isn't "hacking" and... use this to display the image (the link must be the image's direct link that ends with ".png/.gif/.jpg"):

Before thinking about the email if it was something else, ask yourself if you're expecting an email regarding a passphrase.
You might be wasting your time on that.

Emails containing malware and links aren't "that" rare specially if you're actively using that particular email address as a contact on websites that requires registration or subscription.
Can you tell us about your email address' info (not your email address) if it contains a name which is known among Bitcoin users like "Satoshi", "Nakamoto", "John Mcafee" etc because those are often targeted by malicious email senders.

Bitcoin Cash is a Hard Fork, a valid example of a Soft Fork is SegWit which has some software changes that didn't required a new chain upon its implementation.

I can't further help the OP with this, because I'm not well informed (for now) to the "technical side" of Soft-forks/Hard-forks as well, but this link may help: https://en.wikipedia.org/wiki/SegWit

For others who didn't understand the quote:
They needed help because of the difficulty wasn't adjusted right after changing the algorithm.
And now since those ASICs aren't capable of solving the new algo as quickly as before, the current hashrate cannot keep up with the difficulty which makes the
What bugs me is: where the hell did those extra 200,000ETN per block (if mined under an hour) came from? From the dev team's wallets?
So: 26 blocks x 200,000ETN = 5,200,000ETN at most.
Aside from the "Mining Reward" from their Mobile miner, just how many ETN does Electroneum development team have?

Those were validated by all of the nodes via consensus, means "the more, the real~er".

In the end, all other nodes will invalidate that edited block because your node is the only one "voting" that block 3c is valid.
If someone try to make a transaction that uses an input from that block, it will just return with an error like "invalid missing inputs".

Quoted and Verified.

It's a game so I assume that your target market would be teens and young adults?
You don't necessarily need to worry about people who didn't want to deposit for the types of persons at that age and "game preferences".

Just make use of the 3rd party service providers that they probably use and trust like Bitpay, Coins or others as a payment channel to buy "game credits/cash/coins".
With this, they wouldn't really need to trust the game, they just practically "bought" points. (every Game Providers do this)

You might wanna change the "betting" into "reward" by not using bitcoins directly as bets.
If it does, this will just look like a gambling app disguised as a game, and the available market will be slim.

Hope this helps.

Try to minimize the possible problems by deduction.

• Reshuffle the GPUs and see if GPU 4, 7 & 12 are fine on other slots.
• Look at the performance of the normal cards to the PCIe slots where those slow GPUs are previously inserted.
• Do all GPUs got the same bios versions and OC settings?

These are pretty much the basics, other possibility is PSU's connectors and rails setup might affecting the problematic GPUs.

Look again, all prices were now claimed  
Seems like after the discovered seeds got posted, the others became too easy to connect by crossing out the used words (that has no "x2" mark), especially for the 5x consecutive solo winner, but hiding the words is also to his advantage.

---

Connecting them is too tricky because the arrows aren't exactly pointing to the direction of next word.

Theoretically, judging from the total number of words, someone can write a software to bruteforce the possible seeds based on the words from the image. 120~ish, that's a very small library compared to BIP39's or even Electrum's Word list.
Just a possibility, never mind.

Ready for the second round!

Aside from the vulnerable versions, double check the site where you've downloaded your Electrum.
There are couple of fake sites which are almost identical to the original electrum site, excluding the recently taken-down electrum.com (not identical but claiming to be legit) which offers malware electrum downloads.

The official site is: electrum.org - No other alliterations, subdomains or url extensions.

---

If you want to use Electrum, create a new mnemonic SEED phrase using the application itself, offline/online.
Any pre-generated SEEDs can be compromised during the creation or transfer, its security flaw wasn't brought by electrum.

Depends, is your electrum came from the official site? (electrum.org)
And... your version has a vulnerability that can potentially compromise your bitcoins if being actively used.

The mnemonic seed can also leads to different format/"types" of address sets by setting different derivation path.
