Binance will soooner or later get really hacked. Funds are safe will be taken by the back and people and entire crypto will be in trouble. Im not saying a second MTGox but something its gonna happen.
Do not be too pessimistic, think positive.
It is amazing that an exchange that is one year old is now looking at $1 Billion in profits and over 10 million users.
They achieved this success because poloniex, bittrex, cryptopia, yoshit started to provide very poor service, the case of bittrex having blocked accounts of many clients without warning was something that revolted many people and caused many people to stop using bittrex. Poloniex was already ignoring support tickets that his customers sent and yoshit and cryptopia already had many complaints and accusations of scam, so it was already expected that binance or any exchange that offered better services than the old exchange would be very successful.
