Wow! I was a bit scared to pulk some bitcoin off of coinbase and put it in Trezor. But...it went very well! I was very careful and watched about 20 different tutorials on youtube. When I transferred 3/4's of my bitcoin to cold storage I felt accomplished. I just got into cryptos 2 months ago which has workes out well with bitcoin, ethereum, and litecoin. Not bad for a 60 year old!
