Each coin has its own benefits: BTC still holds the scarcity edge with a max total supply of 21M coins by the year 2140 .. LTC on the other hand will have a max total supply of 84M coins, currently the circulating supply is ±54M so as it approaches its max supply I think the value will go up; also LTC along with DASH has a lot of promises as digital money. ETH has no max supply as of now, but its edge comes in the smart contracts capability and investing in the crypto economy.

Indeed diversity is definitely profitable and decreases the risk of putting your eggs in one basket.. remember to always invest money that you can afford to lose.
