No trades for the past hour on poloniex because of "server lag." Its been happening the past few days too. Mods say they are "working on it." Lol.
Pretty sad considering the daily profit they make from fees.
The trading at poloniex is very fast as it is the biggest exchange of altcoins. and even a minute of Server lag can cause someone many dollars lost. and in an hour lag, one can be bankrupt. Poloniex needs to upgrade their servers.
As someone has said maybe they have additional traders registering that causes some lag on the servers. But I agree with you that they should upgrade or get new servers to cope up with the number of traders using their platform. Maybe they haven't anticipated this kind of traders or trading volumes in their exchanges. But this is a good thing for them because many users have been using their trading platform. But I don't think that Poloniex is causing the market to crashed, they just experience some technical issue. That all. I don't worry unless they got hacked and my funds all gone.
