What's your goal with crypto trading/mining

I’m interested in what your main goal with crypto trading and mining is?

Beside of earning money my goals is to secure my future for my kids and grandkids. And also for my self. I don’t trust our global banking system. So better back it up with coins.

My plans is to save up coins on PI network mobile mining + Electroneum until I retire. I’m 30 now so I have at least 35 years left.
