Eh...this might sound great for traders, especially since Binance is an extremely popular exchange, but I'm really hoping they don't allow their customers to use too much leverage. Not only could that ruin a lot of them, but it could also lead to serious price increases of bitcoin and altcoins. That might sound like a good thing, but it might actually lead to a bubble.
What's wrong with a good old bubble? They've never hurt Bitcoin before.
I personally can't wait for them to add margin. I just hope we don't need a verified account to use it.
3x leverage means 3x less collateral required for the same size position. So leverage means I can keep less coins on the exchange. If you know what you're doing, it's the best way to minimize your exposure to counterparty risk.
