Use the SeedSigner and take custody of your Bitcoin. This is a prebuilt SeedSigner Bitcoin signing device, in a very premium CNC milled enclosure made from Aluminum.
The signer is complete in working condition, no building or soldering is required. The only thing you have to do by yourself is flash a micro-sd card (not included for safety reasons) with the most up to date SeedSigner image. A sizeable part of the profits from every purchase will be donated to the SeedSigner development fund.
