Obviously I can google this, but I would just like to hear what you guys have to say as those articles are outdated and may contain irrelevant information.
I would choose Poloniex anytime , Its secure as most of the funds are stored in cold storage , It has the biggest trading volume If we exclude the Chinese exchanges , It's fast , and also have good design and a good support. I don't see a reason why I would choose another platform.
May I ask why you're excluding the Chinese exchanges from your conclusion? I'm probably only going to be trading in American exchanges anyways
are you Chinese and want to deposit CNY?
if not why do you want that?
and to answer your main question, any exchange would work for you. as long as there is enough liquidity so that you can take advantage of all the changes. things that i will check is their fees, and then their volume and then their rules and if they accept traffic from my country!
also i am not sure if you want to trade altcoins or bitcoin/fiat? because polonies is good for altcoins.
