I think that Binance will go bankrupt soon because if hacker attacks and scandals with users database. That is why I want to know what exchange is better to use. I know that changelly is good, but I don't know about them a lot/ Do you know it? What do you think about
Binance had learnt some lessons after their database was compromised by hackers and I think such thing might take time before it can repeat itself again.
There have been some great exchange in operations before binance, I will suggest poloniex or bittrex as an option should binance goes down.
