If i have 10,000$ that is good for crypto investments, i will divided by 3 as follows: 50% will go to bitcoin investment, 30% goes to ethereum investment, and the rest for other general alt coins too.
I think splitting is safe but 10x is not easy. Bitcoin is $60,000 more difficult than ETH to $2,000. Low value will have large space, so I think it is advisable to invest 100% in ETH.
