well you can earn passive income from the right nft-s (at one moment one could earn about 1k$ daily from kongz) , but instead of getting one i staked my eth
yeah real estate would be great , but i never ever sold any crypto (yeah i'm kinda married to my coins) , but i bought my eth around 80E so that explain , but lost about 10 Eth on some shitty nft (could have sold x2/3 back then) , so i learned the hard way .
