Congrats on 10 years, OP! I think 2013 is when bitcointalk first came on my radar, and I wish I'd been more aware of it back then--and bought a lot of it. Here's hoping you backed up the truck in those days that were long before lockdowns, inflation, and a generally more miserable world. If you did, I'm sitting hunched over at the keyboard in the greenest envy.
Unfortunately it could have done more.

It was a good time to buy and invest, but it was also a time of change in mining and everything was still pretty new for almost everyone. So, there were several types of voices that were sometimes difficult for those who had just arrived to make decisions.
Either way, I don't regret anything! I know I could have gone further, but that's okay. By the way, I only regret not having invested more in mining. I'm sorry, I followed the idea that GPU mining didn't pay off because of the ASIC.
But it's all an experience, and today the person is more prepared for what we have today and what we will have in the future.
PS.: I also regret having spent some periods outside the forum. But here we are now with everything.
