If you are a bigginer I advice not to start trading with big amounts! Start with the little ones.Anyway if you want to invest them I belive that you should invest them in freebitco.in. They have been around for 5 years and the pay 4.08% anual comission for your deposits.
Yes, it is very difficult for a beginner to start trading with that amount because he doesn't know how crypto trading will work. Better learn before investing into trading because if you don't have any knowledge about trading you will loose all your money.
