First real Crypto holding scenario. Not meme crypto.

New to the RVN scene and crypto as a whole. I currently have 10,938 on binance my fear is not the hold or the time to wait for growth. I fear using a purchase site not a true wallet. Is binance safe for the long haul. Is there a better way. Examples scenario… 5 years from now I want to sell and let's say RVN hits $1Dollar by this time. Thanks for the thoughts.
