$10,000,000 is a the space equivalent for me to even imagine. Hypothetically if I have $1000000 then I must invest 50 percent in Bitcoin 40 percent in Ethereum and rest 10% in other altcoins (should be top position). Here I will not give myself to invest in any coin you provide. But I wouldn't go wrong with 50% of my bitcoin investment as I'm the highest risk taker and will take the risk between bitcoin and ethereum as I have the highest reliance on these coins.
It's only $1M not $10M though it's still a huge amount but nice composition you got there however with all of those amounts, are you sure? You can't even believe to have a money like that, so why will you only use it all for investment and why not use it first to fulfil your dreams? You know buying the luxurious items and stuffs. I'm pretty sure that once you avail all of them, there will still be plenty of money left in your stash.
I still won't use all of them though but I will set aside for emergency use and for the regular expenses. Back in your composition, you have 10 percent allocation for top altcoins and I think those 3 coins the OP listed are also among it, so why not?
