Smart move, but I wonder what would this change from legal perspective, ie whether Binance would still be required to verify customers ID, since they would be no longer holding funds on anyone's behalf. I'm guessing Yes, as I don't see any government giving green light to non-regulated, anonymous platform, not in a long run that is.
Probably yes, the Binance developers will collect much crypto currencies to their DEX platform and then the government will prohibit their maintenance without verification, so coins of customers who do not want to pass the KYC procedure will remain on this trading platform forever.
On the other hand, this could be just a PR move to prevent people from moving to EtherDelta and alike, or to deter other devs from developing their own decentralised platforms.
I quite often trade on Etherdelta. There are many ERC20-tokens in this DEX. The platform works not quick. Unfortunately, sometimes the new made bid/ask orders do not appear in the list.
