I was following Specter DIY wallet for some time and I like the idea of people making their own wallets from available components, but this is not for everyone and general public.
I think there was recently some bug found in their code reported as false trojan alert, and I don't like the fact that Specter doesn't have any secure element.
Cost of making this device is too high for me to justify making it for everyday use, but as a hobby project it is cool.
