Better keep it some place safe. While I never had any problems with Binance for years, you'll never really know when shit hits the fan. Anyway, congrats on your first purchase! Sometimes all we need is a leap of faith in order to get things where it should be. Right now, the only things you need to do is take the money out of that exchange and kinda forget about it. Focus on what you need to do and come back to it after a year or two. That's what most of us here usually do and it never failed me just yet.
