You can try investing on bitcoin actually but you should think about it first since the value of it is still too high at the moment. If you really want to gain profits and make your money grow, it would be best if you'll search for the top altcoins in the market and choose the one that you see as a potential coin which can be at the top on the next altcoin season. You can also try investing only 50% of it so that you won't end up in regret if ever the coin you invested to will fail.
