And I said we all have different experiences depending on the site. Another example is about Bittrex, which is not listed on your list. Did you forget already all the mess we had some months ago, and their useless tickets system where no one answer you? What about Coinbase? They are pro to provide the support, they only reply(ied) with automatic messages to people looking for help.
Well said. Thankfully, I seem to have escaped unscathed using all of the above listed exchanges with the exception of Paxful, which I never used.
It's probably worth nothing that like all newbies, entering in 2016, I basically thought all exchanges were as good as the other, and dabbled in a lot of altcoins that of course brought me to the smaller exchanges: Cryptopia, Yobit, Tradesatoshi, Novaexchange, to name a few I used a lot! My experience with all of them actually were pretty decent, TBH, then again I hardly needed support requests and probably just did a handful of trades on all of them. I left them completely by 2017, and was still using Poloniex and Yobit well into August/September.
Poloniex because of their loan facility, Yobit because I had a modest stash of Waves and Bitcoin, and when they gave out all those forkcoins quickly, I happily sold.
Of all the big guys, I'm only on Bittrex now for liquidity when I need my alts offloaded. Have accounts on a number of China-origin exchanges, but don't need them. Localbitcoins is where I do almost all my trades now, and BitPanda every now and then.
Sidetracking but the point is... there's no list to be made. Every exchange I feel, has to eventually turn on its customers when they can't handle demand, when poop hits the fan. Do your business, never leave funds on exchange, and you limit your exposure to horror stories.
