Yes and it has grown even more the last few months thanks to Uniswap. Unfortunetly you can not buy anything else then ETH tokens on it. Would be nice to have everything in one place sometime in the future. Once that happens, then crypto is golden.
If current things can work well at Uniswap, then it is not impossible that in the future we will be able to have everything in one place through developments that can be carried out by Uniswap itself.DEX volume has grown a lot since this thread was created in October 2019.

You'll get that with Stakenet's 2nd layer DEX.
They've integrated their own native token: XSN + BTC + LTC, and is working to integrate ETH and it's many tokens next.
The cool thing about this DEX is that's it's gonna be running on their network of 2000+ masternodes, who will act as payment "routers" between everyone who trades on the platform, they will be compensated in fees for this service.
As this DEX is operating offchain you can transact INSTANTLY, with virtually 0 fees involved compared to traditional onchain fees ($30 in some cases for ETH).
All this, while being able to store your coins in the same dApp and being in complete control of your own private keys at all times.
Here's a cool video showing how it works:
