I don't know. When a company starts falling apart like Poloniex, it reminds me of Mt Gox which had a huge issue a year before it fell apart.

It is sort of like when a car makes funny noises, don't expect to keep driving it much longer without repairs. If polo just shuts its doors or disables all activity at some point, it would not surprise me at this juncture. When under-staffing happens, hacks are easier, ect ect
