Thanks for your input on how you sweep the BTC then the forks afterwards once the most important BTC is swept and secured first! Can you or anyone else in here let me know their thoughts on that very risk you describe above regarding it's just a race to get your BTC off your phone and onto a HW wallet? I mean let's say I use Ballet or Coinomi what are the actual risks vs doing it the way you described above? I have no doubt your way is likely more secure but for any security experts in here how much more secure would that way be?

PS: Also at this very movement in time I'd have to go with Coinomi for the BTC as they allow you to set the fees and I'd obviously set them higher for the need for speed but even Coinomi's faster fees is much cheaper than Ballets one size/speed fits all unless they have updated this in their software allowing for us the owner of the Ballet cards to select which fees and how much speed we need a sweep done. Because I do feel Ballet would be more secure given the fact it's a more colder of a wallet than Coinomi just being a straight up hot wallet(a great one but still a hot wallet nonetheless). Would love any and all thoughts!


PS: Thanks for video Krogoth....will watch that soon as I want to learn as many ways as possible!

        The race against time he refers to is as follows...

        If for some reason you have a virus or malware specifically engineered to be able to copy your mnemonic or paper wallet...or and private key...then they can literally beat you to sweeping your coins before you do. So why take that chance when you can sign it safely offline first? Especially with a 10btc coin. Better safe than sorry

         There are also malwares that send your btc to a different address...they switch the addy at the end.

        https://www.coindesk.com/malware-miners-torrents-passwords

        Here is a thread of a different way to carry any btc you plan on sending without actually having the btc on your hot wallet.
        I used to use this method when i met people in person and didnt want to carry the btc on my Mycelium wallet
      
         https://bitcointalk.org/index.php?topic=5106013.0

         Also make sure you download the real clean Electrum

I tried to import/sweep a casascius on the ballet wallet app it didn't work for me. Exodus worked for me for the btc then I used coinomi to claim the forks

Coinomi as well here for forked coins...then to exchange to btc as well.

How does the Revlar "feel" vs. the other ones.
You would never mistake it for regular paper, do the other other feel more or less paper like or all they all about the same?
I know to keep the non tear features it will never have a 100% paper feel but something a bit softer would not be bad.

-Dave

Rite in the rain feels like paper the most...and it tears and a bit soggy.

 Terra and Revlar...look and feel similar.
2148  Economy / Collectibles / Re: TESTING- Submersing paper wallets printed on water proof papers on: December 11, 2020, 03:45:03 PM
I have been using Revlar for a while now.
https://www.relyco.com/products/synthetic-paper/revlar-premium-synthetic-paper/
https://bitcointalk.org/index.php?topic=5141818

PM me your address (I know I have it someplace) and I'll get a few sheets out to you this week.
Works well, very tough.

Many people use it for archival reasons, it was recommended to me by several people who need it and did a lot of research before choosing it.
Waterproof and really tough. Can't rip it have to cut it.

-Dave

Dave...Revlar received...thankyou! Added a wallet in the water with the other two.

Rite in the rain arrived...submersed under water. This is tearable paper unlike Terra Slate...though rite in the rain also sell Duracopy which is similar to Terra slate and I might need to also get for this experiment.

I can confirm through our own testing that these types of paper are indeed water resistant.

Laser based keys do not get damaged in water either.

We tested this by actually placing a polymer Polymerbit note at the bottom of a lake to see if there was any impact.

Also strong streams/jets of water do not cause an impact either from what we saw.

  Thankyou for sharing that...good to know

This is important to note:

Quote
Note that TerraSlate is not compatible with inkjet printers as water-based ink does not adhere well to waterproof paper.

And the riteintherain paper:
Quote
COMPATIBILITY:
    Photo or laser print both sides. Not for inkjet printers.


So true...i tried inkjet and nothing really printed..so it would be very obvious inkjet would not be compatable. Laserprint is the way I am testing...but thanks for highlighting that fact.

This thread had me do some thinking and searching for the best paper I can use for paper wallets and paper wallets for our collectable loaded items as well.

    Only compatible with Laser printers...NOT inkjets.

    I will also be testing another water proof paper by https://www.riteintherain.com/ as well

      Testing Revlar as well.

   I have come across Terra Slate paper touted as The most durable paper on the planet.


   TerraSlate is acid-free and is great for archival use.

    https://terraslatepaper.com/

   https://terraslatepaper.com/pages/faq

   They even place the paper in a dishwasher to test it!!

   https://youtu.be/kWwkd-1LCEc

   TerraSlate Paper has proven to be the world's most tear-proof & waterproof laser printer paper. Compatible with ballpoint pens, copy machines, laser printer and digital presses, TerraSlate is a synthetic paper that never needs laminating.

TerraSlate was developed to be durable, tear-proof and waterproof in order to withstand rain, heat up to 450 degrees, temperature variations, all while repelling grease, solvents and chemicals.

TerraSlate weatherproof paper offers superior laser image quality with the appearance, smoothness and printability of standard paper; and works great in most any standard laser printer or digital press. Most importantly, TerraSlate weatherproof paper is more cost-effective to use and has a much more professional look than laminating.


    Well, I bought some and conducted an experiment to see if this is so....

                   One of our main fears with paper wallets is water damage.
    So I printed out a set of private and pub keys, printed and conducted 2 different experiments..
 
   


         The first was to just dip the wallet into the water for a few seconds and let dry...
Passed with flying colors...was able to scan the qr codes easily and also no damage done whatsoever.

   

       For the second test I placed the wallet under water in a tall glass for at least 12 hours....
Again it passed with flying colors. No damage and QR codes read easily via my mycellium wallet app.

   

    I have to say I am very impressed with these papers and will use for my project as well as any paper wallets that I have.

    As per request from Mbitr  will do as follows>>  I will place under water for 2 weeks...test and place and leave in the glass for a loong time and every few weeks will test and place again...and on and on  Cheesy. Will update this thread monthly on results.

   

   


2155  Economy / Collectibles / Re: Wanted to share NEW IDEA ON HOW TO PLACE A HOLOGRAM WITH PRECISION on: December 02, 2020, 11:59:53 AM
Ok...as promised I have come up with an even more precise way on applying holograms..especially for those with shaky hands!

  I introduce the Krogoth Holomatic... Wink

  You can watch the video of it in action!>>>>  https://www.dropbox.com/s/gusn55d3s65zkfp/20201201_205433.mp4?dl=0

 

  I have labeled each component, where you can buy and explained as follows...

 A) Toggle Clamp 90 Degree   

 B) Hose Clamp

 C) YaeTek Lab Stands Support and Lab Clamp Flask Clamp Condenser Clamp Stands 60CM

 D) Pneumatic Air line 1/4" Od  

 E) Copper Brake Line Hose Tubing Kit 1/4"

 F) Blackhead Remover Pore Vacuum 

 G) 1" suction cup

 H) Permatex 84109 PermaPoxy 4 Minute Multi-Metal Epoxy, 0.84 oz.

  If the vacuum is too great for your hologram, you can always install a small1/4" Hose Barb 3-Way Valve in the airline and bleed some air IN to regulate the amount of suction.

 You do not have to buy from the sites I have shown you, as I have not. These are given as reference in case you need more information.

Not to derail the thread, but I am interested in a similar topic that I was hoping people can elaborate on a bit.

For those that would like to share, what are some companies that make these holograms? I’ve read there are people who make and sell them on Alibaba, but what are some other alternatives? Not sure if people regard this type of info as “proprietary” or not but am interested in these topics and the “behind the scene” type stuff that rarely get talked about such as what Krog brought up.

  You are not derailing anything my friend....please feel free to post as I am sure other will learn from it too.

   So no offense taken!  Wink

What is stopping someone from copying a hologram that your make in order to sell fakes? or better yet, someone at the hologram printing company, printing extra holograms for themselves, then buying your coin, then peeling it and replacing with a fresh hologram that they made without permission?

  Yes great question indeed!

   Lets say you use the same company that made the hologram...and they refuse as they don't want to duplicate any past orders...I am sure there are other companies that will not have any issues in doing so.

If you are worried about you hologram company copying your design or keeping some then you should be doing more research in finding a reputable hologram company.    Good work ain't cheap,  cheap work ain't good.

You get what you pay for..     do you want security or a pretty sticker....

I'm not so worried about a company printing the holograms for someone else, although how would you know if they did or not?  I'd be more concerned about a rogue employee simply making extra sheets or something along those lines.

  Good point...it can happen to any solid safe company.

Don't rely on holograms only... for security....  

If you are making a coin that uses a hologram sticker, what other forms of security would you recommend using?

Laser etched holograms ....  I think have been used..   laser etching changes things......it can be done inhouse


So holograms done In-house, laser etched, and all coin mintage/address info as mj stated above.  Anything else?

It seems nothing is 100% fool proof, except bitcoin itself. Best it seems we can do is minimize as many counter-parties involved with making of coins.

   Aye ...nothing is 100% fool proof, except bitcoin itself.  Couldnt agree more mate...God Bless Bitcoin!
