You need to diversify. Your first proposal was OK. Maybe if you are looking into other altcoins with different techniques I can suggest Ripple and Dash also.
But dont invest all your savings. And one good thing to do is not to invest everything at one occasion. If you are about to invest $10.000 you can decide to invest $3.333 the first every month for three months instead. This will lower you risk!
eToro have launched an interesting Crypto Fund that will automatically invest in the largest cryptocurrencies and relocate once every month. I havent tried it myself but you can read about it here.
