Meet up with an actual expert.
put 90% in a long term investment and 10% in whatever you want. (I'd recommend 8% in a risky investment and then the rest for shits and giggles) Again. Please meet up with a person who get's paid to decide things like this.
Oh and please realize, that in the long term 50k is basically nothing. You're not rich, you're not set for a certain amount of time. You just have a slight amount of money right now.
