I wonder why???

Some speculate that the demand overshot their ability to 'keep up'. This is considered, by most, good news for the crypto market.

Try Poloniex

Smh on this one...The comments sections lit up right before the holidays on this exchange simply holding/making inaccessible funds without alerting 'customers' of any reasons. I stopped paying attention; but, at last record, most felt as if they were left holding air. I'm sure they've gotten back on track; because, I haven't heard any recent complaints...hope so, any way.

Peace.
