You can decide to go mining, but wheter or not it's profitable really depends on how much you're paying for electricity. If you can get that cheap, it might for sure be profitable to go mining.
However, if you decide to go buy coins, I would strongly advice you to not buy all kind of shitcoins that people are gonna sugest. Just keep it to investing in bitcoin, which will be way more likely to be profitable in the long run. It might be more boring, but at least you won't buy a shitcoin where early investors dump it on you.
I agree with your answer !! it's difficult to choose and there are a lot of dangerous shitcoins around.
