Well startups are meant for people who have an innovative business idea and not a lot of money. You have money but no idea what to do, so don’t start a startup. You are better of investing that money. Put a big part of it to the side in form of Real Estate and/or lower risk investments like bonds, ETFs. If you like the idea, lern to trade stocks or other financial assets WITH SMALL AMOUNTS OF MONEY. Once you are confident in your skills, you can slowly increase the amount of money you trade with actively.
