Is investing in startups a good idea? They grow like mushrooms these years and i have no idea how many of them actually legit.
all bubble
but also
technology is here to stay
If you have to, go for cybersecurity or hardware, make sure to not go into medical, maybe if it's really, really promising. Be picky. Make sure the CEO isn't a complete fuckwit because they usually are. Make connections with other investors. When you made enough money, go straight for real estate.
Best of luck.
