I agree that solo Mining is like gambling. But, I believe Mining is not all about making money only. Whoever gets started Mining at some point gets addicted to it. You are a miner, so you know what I am talking about. Some people will continue Mining if their Mining becomes unprofitable. I used to mine ETH when it was POW. But, As you know, Almost every GPU Minable algorithm/coin is unprofitable right now. Still, I mined a couple of weeks before some of the rigs got burned, and I didn't bother to repair them.

Mining is making money and fun at the same time. I don't know how you will take this in your life. It was fun for me. I used to Mine ETH and Exchange them for BTC. Whoever comes new to Mining and hoping to make too much money, I won't suggest them as old miners are getting unprofitable, and energy costs are increasing daily in my area. So, I don't recommend any new miners to start solo mining unless they are extreme passionate about mining.
