Obviously they've supposedly raising the bar and wanted to remind on top. But you will see that they are doing it to take advantage specially that crypto is now moving in a bullish direction. If they can at least cap 10% of new users coming and riding the bandwagon, then good for them . I'm not aware of any other trading platforms with 1/2 confirmations for deposits/withdrawal as well. But if other platforms wanted to do a catch up, I'm sure someone will follow what Binance has done about cutting time for deposits/withdrawals.
You wouldnt succeed if you wont adopt or make such changes to make a better service.Binance do really know on how to step up on the game.
