Although very cool, this also seems like a very dangerous thing! It's an industrial laser in a box with open sides.
A much safer solution is a Letter & Number Punch Marking Stamping Tool Kit, although you need to find a set that has both upper and lower case punches.
Ideal for using a mini private key:

Since it did take 10 weeks to gather 10 individuals, do you mind sending a PM to everyone to make sure they are aware that we are depositing now?
I'll do this tomorrow, to the people who don't see the thread yet.

This is my new return address.

Edit: Would be happier if you could make it VauLT.
Good choice, because lower case L is impossible.

I first found Address: 1VauLTLpA, but it I don't like it much, it reads like "LTL" now. This looks much better:

I'm okay with that. It'll probably be okay to change it again later if needed, if you can sign a message from either the return address used or an older staked address.

they deny to buy my RBIES as promised for a floor price of 1000 satoshi each RBIES.
Does that also hold for RBIES bought at an exchange now? Coinmarketcap shows 781 sat now.
If so, that's a really weird promise from Moneypot!

You are accusing me of fraud and slandering my reputation.
Lol.

The era of free Bitcoins is over since Bitcoins are worth quite a lot of real dollars.
I tell you what: I'll give you 20k free Bytes and 40k free Blackbytes instead if you install the Byteball wallet and say hi to me in the wallet's chat. Use pairing code A8JlWkrGQd9XxG7VPAtyWs2uzVuVqMlJOBpu8rusG8v0@byteball.org/bb#d0cJPpIwPsd6 if you want this.

For the rest: forget about mining, work to earn Bitcoins (or dollars to buy Bitcoins), don't beg. It's also a violation of forum rules, we all know you have neither the means nor the intention to pay it back.

Thats a forum policy.
You joined 5 weeks ago. That means by now you could have been Jr. Member already, able to post images, if you would have posted enough without spamming.
Newbies can't post images to reduce spam on the forum. We've all been there, we all went through it. And if you start a decent thread as a Newbie, there's always someone kind enough to quote your post to show the images.
Now you've got yourself red trust, lost money, and still can't post embedded images.

I've learned many years ago never to trust screenshots.

Unfortunately he doesn't recognize the address I sent my coins to so it looks like I landed on a phony blender site and got scammed.
Address 1NkkM3zBRq2nSzXEh94gJ3dQXL1PLzJwV2 has been used before, in 2016. I'm pretty sure no mixer would ever reuse deposit addresses, so you must have been tricked into using a fake site.
25150  Economy / Exchanges / Re: Bittrex Fees on: September 26, 2017, 10:26:42 AM
Just wondering anyone else experiencing wrong figures or anyone can explain this to me.
I know its minor but these can big losses when you invested alot.
Can you post a screenshot of your Order History? Make sure to crop the screenshot so it doesn't show any personal information.

I just checked my last trade, and it quite accurately took 0.250% in fees. Exactly as it should be.

I suspect you posted the order at 0.00009494 but it got filled at a (better) 0.00009495 price because there was a bid for that price on the order book (somebody was willing to buy your coins for more than what you asked for).
This could explain it indeed. Don't assume the exact values you enter are what you sell/buy for, your order could also be partially filled at several different rates.
From Bitman911's example, I calculate 0.24% fee, so indeed it must have sold at a better rate than he asked for.
(7.61314167*0.00009495-0.00072106)/0.00072106=0.002507

Bitman911, once you're convinced Bittrex doesn't try to cheat you, please change the title of this thread to reflect your new findings.

Well, i just got my 385 tokens np, so maybe not a scam afterall
I never received mine. But even if I received them, it's still a scam.
The promise was $10 worth of tokens, if now 75 tokens is worth $0.75, that means they waited long enough to cash out their own tokens before giving out worthless bounty tokens..

In addition, it's very nice to see Brand-new accounts registering here just to say they've received their tokens. That's not suspicious at all!

Bitcoin could hit $100,000 in 10 years, says the analyst who correctly called its $2,000 price
It's important to note what the bold part means: it means nothing! They're trying to add credibility based on something completely irrelevant. Hundreds of analists all make seemingly random predictions, and because of the large number of predictions, many of them must be true.
That doesn't necessarily mean the analist is right again in his next prediction. It could have been luck. Given the number of predictions made, it's even likely that several "analists" are right several times in a row.
25154  Bitcoin / Development & Technical Discussion / Re: Problems importing private key from paper wallet to bitcoin-qt on: September 25, 2017, 03:33:29 PM
You emphasize the before, importing an address cannot be done after funding the paper wallet?
Of course you can always import any watch-only address. The only benefit from doing it before funding it, is that you don't need a rescan.
If the address is funded already, any import requires a rescan to show an accurate balance. Importing unfunded watch-only addresses saves time, that's all.

Quote
And if I hold private keys with some UTXOs at the corresponding address in the bitcoin-qt wallet and one or several watch-only addresses as well and this is all intermingled together to a single balance, how can I differentiate what values are spendable from the bitcoin-qt wallet and what belongs to the paper wallets?
Bitcoin Core adds a new column "Watch-only", like this:
25155  Economy / Speculation / Re: Amazon to accept Bitcoin as early as this October? on: September 25, 2017, 01:46:33 PM
... I think that this will not happen. The tax authorities will not be able to formally calculate and track such transactions and I think they will be against.
I expect Amazon to instantly convert the Bitcoin into the local currency, just like any other large online service that accepts Bitcoin. Taxes are calculated just like any other sale.
If I continu speculating a bit more, I expect Amazon to be big enough to create it's own payment processor to exchange Bitcoins without paying a third party. They may even start a competing Bitcoin payment processor for other businesses, just like many businesses sell their products through Amazon.
For large orders Amazon may even save on creditcard fees if it's paid in Bitcoin.
25156  Bitcoin / Development & Technical Discussion / Re: Would there be a way to put a lock time on all successive transactions? on: September 25, 2017, 12:01:58 PM
Just looking at creating a colored coin that would represent equity shares in a company. One way to comply with SEC regulations is if shares of a company can only be sold after 1 year. And any sale of that share beyond that also needs to be held a year.
Since you're looking broader than just Bitcoin: Byteball offers regulated assets:
Quote
Regulated assets
Regulated institutions can issue assets that are compatible with KYC/AML requirements. Every transfer of such asset is to be cosigned by the issuer, and if there is anything that contradicts the regulations, the issuer won't cosign.
You can probably set up a bot to handle sales-requests (but I can't tell you how exactly).

give your family an empty wallet. make a signed transaction, unbroadcasted in your safe deposit box. if you die, they can broadcast it to their wallet.
Nice idea. Never thought of that. How do I do it?
It's called an nLocktime transaction.
read that idea but also the dangers it poses. Namely the biggest danger being that Bitcoin forks in such a manner that "old signed" transactions are no longer valid which would leave my "heirs" with bitcoins neither them nor anybody else can spend.
You can reduce this risk by using a smaller time frame: move your coins to a new wallet every year, and create a new signed transaction. The lower you want this risk, the more work it is for you.

give your family an empty wallet. make a signed transaction, unbroadcasted in your safe deposit box. if you die, they can broadcast it to their wallet.
The bank staff and family member can work together to steal your funds.

For example, even a vault needs some usability in order to be a viable solution for storing your paper wallet.
When using a vault for cryptocurrencies, you can use OP's #7: "metalstamps" to just hammer the passphrase into the vault itself. Hammer it at the back, don't even lock it, no thief is going to steal a heavy wall-mounted empty metal box.

I would start with creating the private key for the cold wallet with a coin or dice instead of a computer rng.
It may be worse way than using rng. Especially with coin  Smiley
Throwing a dice is quite random. Just throw hard enough and make it bounce through your room if you're totally paranoid. Among others this video explains how to use it. But, creation of private key is not really the scope of this thread.
25159  Bitcoin / Bitcoin Technical Support / Re: Scan QR code of paper wallet? on: September 25, 2017, 11:00:40 AM
Just typing private keys takes a few seconds, I get it right at first try 50% of the time.
Using a phone, saving to SD-card, and copying to your computer seems like more work to me.

@jackg - I have ordered a webcam for future paper wallets, so I can use that on my air-gapped machine.
How do you transfer the coins form the air-gapped PC? Sign a transaction, broadcast it on another PC?

Yes I have a few spare old android phones. Going to reset it before I use it.
I never trust Android to completely remove data from the phone, but as long as it's offline and you never use the same private keys again you don't have to destroy the phone after your session.

copy private key and send it to your facebook messages
No. Just no. I know it's been said before, but let's emphasize it again: don't recommend Facebook messages when someone is working securely on an offline computer. Always assume Facebook stores all your data for eternity.

Since we are into paper wallets.  As I trust them more than anything else.  I will let you know about OMNIWALLET.COM
A web wallet is the last thing someone on an air-gapped PC needs. It's .org BTW, not .com.
