EOS is certainly an exciting project with a lot of potential. It's token is still very volatile though so it is really like a speculative stock at this stage. I'd prefer to see something more solid come out and the ICO a bit further progressed before investing too much but it's definitely on my wish list to buy when I next go bargain hunting.
I'm looking to scale in as well. I like to put in a few bids and let the crypto volatility do its thing.
