Recently the SEC (Security and Exchange Commission) announced a decision that puts decentralised exchanges (DEX's) firmly in their crosshairs, with EtherDelta being the most high profile DEX affected so far.
Today the Aphelion team announced that they have disabled their mainnet DEX causing the value of APH to plummet to less than $0.01 down more than 70% from its previous lows, CEO Ian Holtz made the announcement via a blog post on Medium stating that "new SEC rulings, disastrous market conditions, NEO tech challenges and diminishing cash flow" culminated in the DEX being deactivated.
It is a shame because i felt that Aphelion was providing a solution to the problem of never-ending hacks on traditional exchanges and it was (and kind of still is) a promising endeavour, though there is no mention of cease and desists being issued by the SEC it seems that some are being proactive by stopping what they are doing until they are sure they are compliant.
