What is unknown to you is not really "unknown".
In fact, if I had a nickel for every time someone said "Mike, I have a great idea... and no one else is doing it! It is totally unique!" I would have a truckload of nickels. They believed they had discovered "the unknown" to which I was the bearer of the sad news "Sorry - you are already late to the game."
If something is unknown to you....
Don't travel alone.
Then the next question will be "OK, sounds good. Who do I trust?" :)
