Bitcoin Forum

I have been using this device flawlessly for almost two months now, never missed a trade, never lost any BTC or ETH. All transactions have been recorded on the BTC and ETH blockchain. Its been totally offline and secure. my private keys are generated offline and only seen by me. My BTC/ETH addresses are easily stored on SD card (or paper). And all the addresses I have ever created or currently being used are saved in offline file folders and conveniently organized for quick access. I can generate addresses and store BTC while sitting in the park or in traffic, and I have never needed a PC or laptop to do this ever. . .  Video update for the last month can be seen here, . . . https://www.youtube.com/watch?v=2flm-JuE4qM&t=7s

Generating bitcoin address pair on bitaddress files in mobile is quite tricky, you don't have mouse to move around. You have to keep touching the screen several times to make one pair of address. However your idea of making completely offline bitcoin address with handheld device (even with your old phone) is very nice.

Thanks for video but why you have posted this in trading discussion?

When I read the description for trading discussion said "delivery methods"  , the other topics didn't seem to fit. , Was there a better area for it?

And yes it takes a while with the phone and touch screen, This is a beta version so to speak. The bitcoin paper wallet offline runs faster with touch screen as it allows you to drag your finger as well as touch. but it doesn't do the copy and paste as well. Its all somewhere in the coding. An excellent version can be made. I would like github to make a full android wipe and Linux install simple program that can be added upon later with versions that are leaned towards security, or using the camera to take background pictures for paper wallet designs, etc. . Since I have two identical devices now. I use one for my use while the other is used for total erase and new installs. I have changed some of the programs as I find new ones that work better for what i am doing. such as I have quit using opera mini web browser for offline web pages, and i am now using a faster basic offline web page viewer. I now also use the offline eth address and have moved eth into cold storage. Its nice cause now all my crypto is totally off coinbase and into secure cold storage. How did you know the touch was tricky. have you tried this?

Yes i have tried it with bitaddress.org (not offline) in my phone, and i know it is quite hard to generate a pair. But i usually try to generate more than 1 bitcoin address on one try so that i can get nice pair of addresses to use in future.

Yes, I always generate blank addresses now for later use, I try to have at least five.
