If I not only don't understand something, but also believe that the people flogging that thing don't understand it, I'm certainly not touching it myself. So, no, skipping ICOs, thanks.
Exploiting the hype, on the other hand, I am entirely comfortable with.
I've flipped a few GPUs on eBay and easily doubled my money, and am currently trying to do the same with a small number of hardware wallets. Further, I'm holding a couple hundred bucks each of ZEC and ETH in anticipation of volatility, potentially from the shakeout of current BTC movement, from ETH moving to Proof of Stake, or from just the nature of these (currently, albeit not by intent) all being speculated investments that I'd be willing to go long on--so if I miss a spike, I'm comfortable waiting a year or two.
What a weird space.
