Thank you for the wealth of information which you shared in your lengthy response. I totally agree about Ethereum and I'm purchasing that along with litecoin to hold onto. I've only invested a small amount into Bitcoin so far but probably won't dump a huge amount in it, unless it drops low enough, as you're right about it's ability to recover quickly.

It really does take some time to make an informed decision with crypto, especially with altcoins. I want to get a secure offline wallet for my crypto before I start doing any serious investing, and have been thinking about using an SBC as a solution.
