I was tempted to buy this for a possible pump and dump scenario (you know what I mean) but when I looked at the name "High Performance Blockchain", I said ugh, so generic, I'll pass.
Reminds me of the local Chinese-owned establishment/stores near my vicinity like "High Grade" and "One and Only Marketing", so lame, personally I don't hate Chinese brands but it's quite easy to gauge their "product quality" by the way they name their brand.

The hell.... It's plain-sight obvious.
Who would start an airdrop if their coins were already distributed.

Why do they even need to activate Windows if there isn't any disadvantage in mining?
Unless you plan to use the rig to something else.

Those are positively hacks, the most famous one is KMs@rain activator that is a malware which is widely spread among forums and "hacking" sites.
If you meant those free/cheap serial codes and product keys, they aren't "legal" at all, those were just shared by some users.

Yes it is safe.
It is impossible for someone to find your private key just from the transaction id/hex.
In fact, Raw TX are even displayed on block explorers like: blockchain.info (?format=hex added) which doesn't expose anything about security other than the transaction history.

With all the replies regarding being centralized, what are the options for a Country to have its own blockchain-based digital currency?
I have mentioned this before: Create their own cryptocurrency or make use of the existing Digital Currencies.

A potential national currency needs to ne Centralized governed by them, whether you like it or not it will be centralized.
Why do people complain, will they use it? If they came from China, it may just replace Yuan not the digital currencies that they are hodling.

Yes it is, I don't know why most of the replies are negatives.
No cryptocurrencies were harmed or altered, a new unique one just added.

How about this address: 1MaUVgXCgdXLkmXwQ4WDek5yaK86zYXw2q?
I saw a thread saying that this might be the one responsible for the price dip. Since Last Year till February this year, it's been accumulating huge amount of Bitcoins.
Look at how fast and frequent the user sold that 100,000BTC. Although, it looks like another exchange cold storage address.

You are missing a zero. $12,000 previous high.
and, and <$10,000 within three months can be considered stable for Bitcoin. 

Reminder from a fellow Windows 10 user:
Activated or not, Windows 10 "Windows Update" is like a torrent client.
Means that the previous update you downloaded are constantly sent to others who are needing them (like downloading, seeding and leeching)
Windows Update can't be disabled in the settings however, can be disabled in the Services.
The Torrent-like behavior can be disabled too in the advanced option. If you want to save bandwidth, disable it right away.

Why do we even need a portable version?
A stand-alone version is available that can be used for removable disks.

Simply make a copy of the wallet file in the same folder where the stand-alone executable was located in the flash drive.

Anyone already tried this?

Just bitcoin, but all digital currencies in total can match the power consumption of banking systems.

But enough with the environmental damages, it's been discussed several times in the past.
Bitcoin blockchain is way more convenient than banks however, if banks cease to exist due to the introduction of blockchain in financial sector (that is impossible during our time) the problem would be less employment ratio.

Bitcoin's hashrate could grow too to consume even higher resources if mining become more competitive and if newer generations of ASICs failed to solve power efficiency.

During my regular browsing in the Electrum Board I came across this user: GiGa#
who is a newbie and yet he already got the 100 default merit for Full Members which is not received nor displayed in his merit summary.

One theory I am thinking is he was a Full Member before January 25, 2018, previously banned which deleted all his posts then successfully recovered his account just recently leaving 100 merits to his account.

Or is it just a bug?

Any thoughts?

Possible but still, has downsides.
I've seen a lot of API and sites that offers browser mining and most of them are for monero which must be based from Coinhive's code.

In my own experience, the most noticeable downside is the hashrate.
Regular (installed) Miners often outputs higher hashrate than browser-based mining. Also, the tab must be kept alive which isn't a major issue, but most of the time I'd been accidentally closing them.
There are sites with lots of bugs which when you stop mining, after re-opening the site (homepage) the cpu and gpu kicks to sub 100% at idle, means it's mining without crediting you due to a bad coding.

Then after some updates in my AV (Dec'17), most browser tab miners were blocked needing exception and deactivation hassle. I stopped trying since it's not convenient anyways.

If you have an access to the wallet for signing and verifying signatures, yes.
Next time, provide a signed message along with your address.
Quoted and Archived.

Most of my GPUs are secondhand, in my case, yes. Most of the time, they only need thermal paste reapplication.
Sometimes, the problem comes from a worn-out GPU.

For brand new ones, we can never tell if the product they handed you have defects or not. Those have never been tested to a stressful usage.
Only brands can tell, the products from a reputable brand could produce less defective GPUs than the ones from a substandard brand.

According to the (unofficial) Rules:

@Mame Those accounts (including the OP author) must've been bought.

But I highly doubt that Theymos will grant those types of requests.
Imagine if someone bought an account and he didn't like the username, if it is that easy for a username to be changed, a granted username change request will act as a promotion to account sellers.

Can't verify your signature.
SdqhuDo5cTHe2ABSbaKinoqZEKRp2zQqrU is not a Bitcoin Address,

Nope, once other wallets support bc1 addresses, they will eventually be able to verify those addies.

Same with Windows7 using stand-alone executable. When Memory-pool is selected, it always return to ETA after opening the preferences.
When the transaction fee estimation was set to Mempool, the scroll displays ETA?(1.0MB per tip).
When ETA was selected (from Static), the scroll displays Static (Within 5 Blocks).

Quite easy, them, the software engineers and the developers are the first persons to mine the succeding blocks.
The are no competitions in discovering the next blocks allowing them to hurdle a lot before the miners join in.

However, the "forked" coins from the previous blocks can not be claimed by them, without the addresses' private keys, even developers cannot claim those forked coins.

Hello, I generated a "24 words" seed from iancoleman's BIP39 seed generator, not 12.
Which I've used to make my SegWit  P2SH-P2WPKH electrum wallet.
Question is, will there be any implications to the addresses generated or difference to the one which is made from a 12-word BIP39 seed?

I suggest you to read more topics from this board Mining (Altcoins).

But since you wanted to start right after, for a newbie, start with NiceHash.
They even support rigs with one Supported GPU like GTX560ti (if you're tight in budget), ofcourse, the stronger the better.
Go to their profitability calculator to look for the supported devices.

Once you learned more, you can use the rig for pool mining.

This is too weird in every way.
Same idea can be done with fiat but no one does, simply because it's not conventional.

A regular vending machine that accepts Bitcoin doesn't even exist, where did you get the idea of a "charity version"?

Want to help the poor using Bitcoin?
Reach out to a charity foundation that does that and send them the funds, it wasn't that hard for anyone to sell Bitcoins for fiat or products.
It comes down to their credibility, if you trust them help them or advertise the foundation.

Or go to the forum's Lending Section and do the charity work. :P
