To be honest, I would not not use my whole $1,000,000 to invest in Altcoins. This is so risky as you never know the possibility of making profits. Altcoins are damn so risky especially the new ones so it's best I either split the money into 4 or 3 parts the bigger portion goes for Bitcoin then the others go for different Altcoins. When dealing with Altcoins you don't need to put all your eggs in one basket.
