MIKE!! So happy to hear from you!
I did a bunch of tests on my existing equipment (no investment in new equipment planned currently). I found out that at the time, ZCash would be the most profitable for me. I’ve been mining it at home since. The electricity cost has been roughly zeroing out the profit made just on ZEC, but I’m slightly profitable so far by trading ZEC with BTC, ETC, LTC, and others. More of a hobby than anything, and I should really re-test to see what would be most profitable now.
I’ve never even considered solo mining. My gut feeling was that a regular stream of coins is worth the fees, knowing how you’ll stand in the future when trading. I could be wrong, and will look into solo mining.
I only wish I had kept all of the BitCoin because I spent almost half of what I had accumulated at one point. I was hedging my bet though - probably a wise thing to do.
That’s the story for most of us. I’m not disappointed, no one could have honestly predicted prices north of $10K. I had around 85 bitcoins years ago, and cashed out at one point and made $700 net. Can’t be ashamed of that, even wishing I had even a single bitcoin lying around that I never touched.
