Diversification is the basics of investment!
It is not a POKER game, we are investing in some projects, you shouldn't get too motivated to throw all your money or too bored and ignore it.

Also, it is a very old saying: "Don't Put All your Eggs in One Basket" which is completely true.

If you are someone who invested ALL his money in Ethereum, someone diversifies it and put some to an ICO which get 40x of what he paid, and you barely get about 2x!
