Even after reading bunch of suggestions from fellow hackers, I would still focus on your view of the world and what assets have value to you.

My main core would be real estate and stocks. I find them safe, real estate more than stocks. Though stocks are connected to products that produce value. For retirement maybe DGI might be interesting.

then probably gold, diamonds, etc -> to store value, not to expect huge gains

p2p lending -> can do ~10% annually, but it's risky.

crypto - risky bet, as you are in software, small % might make sense. Choose the coin that makes most sense to you as a software developer
