The Bittrex chart stucks sometimes. Chart won't get updated relfecting the current value. This happens most of the time when pumps'n'dumps happen. Figure it out by yourself. Take Telegram and go into some pump'n'dump channels and look carefully when the chart gets stuck ;)

...and yeah, got the same feeling like you about Bitfinex.

But what is about Binance? Pls tell us more.
