The best place in where you can invest those funds is on the altcoin market, but i would suggest you to put that money on bitcoin before the next fork on november 11, you are going to receive coins for free, i am going to do the same, i have some fiat and i will buy some bitcoins in order to receive those free coins, and this is why the price is going to increase by a lot of money, because the market is going to be extremely hyped because of those guys who want to buy bitcoins like me.
just invest that money on bitcoin ,you will never regret about that.
