I've heard of Ledger Nano S. Will definitely look into it. Thanks!

Alas, it's too late. I've been blogging there for over a year and I love it. LOL
I guess, if you like supporting shitcoins and earning a couple of bucks it ain't that bad.

Very shady. Use Gemini (US) or Bitstamp for EU.
I ordered a $30 book: Mastering Bitcoin. Unfortunately I have a community mailbox and someone else needed it more than me. GRRR. I'm learning something new every day. Kind of wish I paid attention to the Bitcoin geeks about 7 years ago. Yes, I'm an idiot.
