What are the implications of regulating decentralized exchanges?
It's quite difficult to think about the implication to regulating dex consider people trade directly from their wallet and the amount that already traded will be also coming back to their wallet.
Do you think it's possible to enforce regulations on them?
I do think that it's possible but regulation will be quite difficult to be applied because people are calling the smartcontract to trade their tokens. The only possible thing to force the creator of dex to put verification may be
Can DEXs remain decentralized enough to go above the law?
Dexs can and why not?
I do think it's possible. If they did it to etherdelta, they could do it to any dex. It is however pointless doing it and it must have been in their minds as well because people will just find a way to trade to another dex which will lead them to countless DEX that could be created a thousand times a day.
DEX are not fully dex in a situation where they could be stopped by SEC. Until the website domains and servers are accessible by authorities, it will not fully become DEX but the mobile apps of these DEX and software like Blocknet are likely harder for them to stop.
