Thats not how diversifying works maybe you could invest in 4 cryptocurrencies go for bitcoin for sure and choose on ripple or neo Then you could risk on some new ICO for better chances of increase profit
In most cases that it needs to shift for another coins is due to price trend, is just the way to keep safe from losing at all than to save a little. I've tried these before and seems to be effective, but still need to be smart or else you've got nothing in the end.
