I own some, because I bought during the ICO, but there are two things that prevent me from buying more:
a) Why pay them 2%+ in fees to do this when I can diversify a portfolio given their public investment breakdown on a certain exchange given their numbers and avoid the fees? i.e. I could go on poloniex and own 15% btc, 15% eth, GNT, DASH, XMR, SIA, and their other coins in the prescribed ratios

b) How is our money insured? Crypto may or may not be in a bubble right now, but if it bursts and the fund drops a huge amount, what prevents the people holding our coins from running?

Also curious how the fees work, are they amortized after someone sells? Or on a regular schedule? i.e. if we have $1000 at start then $2000 end of month one, do they deduct fees then, and if it drops to $1000 again we lose money despite fund being even?
