In my opinion that you take off your tokens within the short time, at that point it'll affirm unless you need to take off for a long time like for case, more than three a long time or long term. Also it depends on the trade itself, how that trade can provide security to their member, so we do not need to anxious to urge hacked. I believe any leading exchnge like,binance, hitbtc,probit,bittrex,etc still not safe because online and It is necessary to activate high security for account to avoid risk of hacking.
