15  Economy / Collectibles / Proof of Keys Mosaic - limited run of 10 on: January 01, 2019, 04:03:25 PM
Happy New Years everyone!   Cheesy

To celebrate the upcoming 1st annual Proof of Keys event (Jan 3rd), I asked the artist Corinna Barrell to make a limited run of 10 custom mosaics.  The pieces are 27cm x 24cm (about 10.5" x 9.5") and they will be numbered.  They cost $100 plus shipping from US.  (All $$ go to the artist, I'm not getting a cut.)  PM me if you want one. 

The goal of this event is to raise awareness about the importance of holding your own Bitcoin private keys. "Your keys, your Bitcoin; Not your keys, not your Bitcoin!"

Info about Proof of Keys here:
Great podcast with Andreas Antonopolis and Tracey Meyer discussing it here:

Thanks   Cheesy

Hello fellow crypto collectibles addicts  Grin

I want to make a wall-mounted display for a variety of my collectibles.  Some low-value coins, Kialaras, paper notes, stickers, etc. I'd like to show the breadth of creativity in this space. (The really valuable stuff like Cas coins will of course stay in a bank vault.). I'm curious if anyone here has any suggestions or even photos of how you've done something similar? 

I'm thinking of roughly 3' x 3'.  (That's roughly 1 meter square for our friends who live outside the US 😀)

Thanks in advance!
18  Bitcoin / Development & Technical Discussion / Looking for advice on how to get rid of dusting on: November 19, 2018, 04:00:52 AM
Hi everyone,

I recently discovered some small Satoshi txns that were sent to my wallet without my knowledge.  I'm guessing these are a "dusting" operation.  I'm not doing anything illegal so I'm not worried, but I do consider this to be an aggressive invasion of privacy and it pisses me off.  My first reaction was to find the companies that do this bullshit and spray-paint their developers' cars so they can see what it feels like.  But then I calmed down 😜.  I'm now looking for advice on how to get rid of the dust UTXOs.  My wallet is held on a Trezor.  Thanks in advance for any advice you can offer.
