Probably, 30% of this money will be spent to Bitcoins. The other part will be spread between the altcoins that I trust. Suppose, it will be Ethereum, Crypterium, TRON, Monero, Stellar, and ICON.
I think this will differ with every single situation depending on the investor. Someone will utilize the whole sum in bitcoin and some will do what you have said, division and later one is more suitable.
