Just invested...

I just invested some btc in Waves and Rise ICO. Good idea?

Also going to buy some LISK at launch...

It could go both ways.  Who knows what direction these ICO coins go or if these platforms really find any real world use or not.

But personally, I have never invested in an ICO.  I usually wait until these coins are actually traded in an exchange and see how they go.  The thing to look out for first is the volume.  High volume is always good.
