I have the Logitech MX Master Keys, although I use a receiver with it instead of Bluetooth which is also connected to my Logitech mouse. The keyboard is good for people who like the shallow press laptop like keyboards instead of a long travel mechanical keyboard. It's similar looking to a Magic Keyboard but the keys have dimples in them so it's more comfortable.
I sold coins along the way to cover initial investment and then exited the majority of my holding at $500-1500. I sold my final bitcoin in 2017 when prices were sky high. If I had sold everything at peak I would have been extremely wealthy. Maybe next time. :)
