Yes, I am totally aware that the price will be (almost) the same on Poloniex and Bittrex. This is simple arbitration and that was not the main question.
The main question here is to find out how Bittrex coped during the meltdown on Poloniex. Maybe if this madness happens again I will go to Bittrex instead. What happened on Poloniex was inexcusable.
Thank you for your answers, keep them coming!
sadly there is no perfect platform to trade on.
poloniex is big, it has a lot of coins listed and lots of high liquidity. also it has a very good set of API methods which makes things very good for traders who use bots.
but they are shady, they pump altcoins themselves, they go down very easily because their servers are weak compared to the large number of users they have, and their platform (website) is shit in my opinion since it loads slower and the charts are way too simple!!
bittrex is big enough, has most coins, it has a handful of coins that aren't at all listed on polo such as FTC and PIVX and that gives it an edge. it is secure, the charts (website) are awesome. the site loads fast. they also don't require verification of your account. i have not yet experienced any downtime with them. but they had some.
however, their API is not so good, they don't give chart points in their API and don't have sockets.
