An absolute shit load and we've only just seen the tip of the iceberg. I personally got out of ETH way before the HF and although I got temped to jump back in to ETC to take advantage, it's way too risky.
Happy to sit out, hedge in other assets and invest in some upcoming Dapps on the horizon in the near future.
Bitshares is awesome but their marketing sucks and unfortunately this is 50% of your business.
