I went with a 75% BTC and 25% ETH for the time being.  Of course neither one of them is doing very well at the moment.  To answer an earlier post, I've been into BTC for several years.  I first bought a bit at $800 and added a little more around $3000 and continued up to about $12000, so I've made a bit of profit so far.  But BTC has slowed down while others have been galloping ahead, so thought it might be time to diversify.
