This tweet proves that binance will add the margin trading on their platform. But I am not more familiar with margin trade and I did not try yet. May be margin trade is risky for newbie and easy to experienced person. If binance will add the feature hope more people will familiar with margin trade and will try to do trade.
Yes, they will add it because it's the official account of binance. I've struggled of looking for that tweet because it was covered over by new and recent tweets.
I thought those articles that I've found out were fake but after reading, most of them redirected me to that tweet so I can say that it's for real.
