Call me old fashioned, but when it comes to investing you should stick with tangible things. If you buy stocks or gold or invest in real estate you own something tied to your name. With crypto and NFT it's not really something that has inherent value and is very volatile. You hear about the winners, but never the losers. If your young like 20s maybe you can be risky, but 30s I would say be more conservative and don't put anything above 5-10% in risky plays. Put the rest in index funds and go to sleep as compound interest does its job.
