Put collectively a do-it-yourself chilly storage and signing machine setup. All the things may be bought on the retailer with money or made your self so there isn’t a buyer record linking you to a bitcoin chilly storage and signing machine that may be leaked by some third get together. Seed Signer and Specter Desktop are each open supply tasks that I paired with a Raspberry Pi 3 and a few in cheap equipment. I obtained the mallet and stamps on the ironmongery store and made the seed plate at my job. Excluding the Raspberry Pi that I fortunately had laying round, all the things was bought for lower than $75.
Please bear in mind to help and donate to open supply tasks.
