I agree with others - if 5ETH is your total "crypto basket," then I would definitely not put it all into ICOs unless you have the majority of your wealth in other, much more secure assets.  This is what Nassim Nicholas Taleb calls the Barbell Strategy --> https://fourweekmba.com/barbell-strategy-taleb/

Honestly, if it were me, I would skip any ICOs and look for an already-live project that is being used today.

The ICO market is weakening, so I think you'd be safer with an actual livenet coin.
