You can always go to coinmarketcap.com and see the various exchanges for each coin.
-Which have (legal) US compliance?
-Which have options/futures or other contracts?
-Which have red flags (holds on withdrawls for mysterious reasons, like Poloniex, for example)
-Which have security red flags?
-Which have actual support help?
-What countries are they based in?
I want able to find on their site which states they do support so you might want to email them first before setting up an account you can't use.
They have not been hacked. That's the only thing going for them, as far as I'm concerned.
We are 100% non-rent seeking.
In Ethdex we incentivise Trading platforms by allowing fees to be charged in Eth, the natural currency of Ethereum. Not by creating a token and forcing its utility (ala ZRX and 0x).
We also support Multi-Relay, which is something 0x does not support. As a maker you can submit your order to every trading platform, every slack channel and every subreddit. Other platforms cannot do this.
We also don't have any obligations to VC's to ensure they make profit.

Poloniex, I don't trust with the majority of my funds for various red-flags that the community has presented and Bittrex doesn't seem to have any retail presence (other than being in an abandoned strip mall in LV).
Gemini is founded by the Winklevi twins.
Previously, my setup was USD<>BTC at Coinbase, and BTC<>AltCoins at Bittrex… Might try some of the other suggestions for USD<>BTC in the future.
The largest one in Europe seems to be Kraken. Bitfinex was one of the first to let people use leverage, but nowadays you can get it on most of them.
If you want to withdraw fiat, you'll need to have a verified account (think sending them a photo of your ID/passport and some invoices to verify your location).
Interview with the CMO - http://news.8btc.com/8btc-interview-binance-cmo-he-yi-talks-...
bitmex.com - (futures exchange) - This is a gem. They're extremely professional. Every feature seems throughly considered, e.g. margin positions are valued based on global indices, not the local princes, to prevent flash crashes. The API is the most feature complete I've seen. One thing that bothers me is that Bitmex seems to have a conflict of interest, since they run a trading bot ('anchor market maker') on their own platform.
etherdelta.github.io - (ICO tokens only) - This was designed so that the exchange owner never controls your tokens, an Ethereum contract does. You decide whether this reassures or frightens you. It supports all tokens which is probably the main reason I used it (besides being a cool proof of concept). The in-browser UI is pretty bad.
Currently I am using Bitfinex and it's working pretty well!
Cryptocurrencies have limitations against alternative payment systems: (1) they are "push" only (2) have a huge buy/sell spread and (3) risky fluctuation, if they do not have at least anonymity benefit why should I prefer them to UDS, EUR or GBP?
Anyway seems that there are ATM for bitcoins, never tried one (https://coinatmradar.com/). Did anybody already tried one?
I'm not aware of any other exchanges that can trade in NY right now
I haven't had any availability issues with their backend (i.e Coinbase) and their support staff seems responsive to the fact that the trading GUI needs an overhaul (2 separate pages for buying and selling ETH).
Bitfinex is closed for US customers.
