and unfortunately, decentralized exchanges can't begin to compare to centralized exchanges in terms of markets offered, liquidity and functionality. it's simply getting harder to safely hedge or profit from crypto markets. that's nothing to be happy about.
Decentralised exchanges are still in their extremely nascent stages. I wouldn't give up on them yet. At some point relatively soon there will be a truly compelling option. I certainly am not tempted to use any of the current ones.
It's irrelevant asking whether crypto needs regulation. It's going to get it regardless.
I think the ICO shitshow has done more than anything else to bring unwelcome heat. Had that not blown up there might've been more time available for crypto to infiltrate things under the radar. That chance is now blown.
