With that decision they've made, it's already a big help to them since they've been placed with too many sanctions that's already affecting their economy.
It's not the citizens and customers that they're against with but the action of their government towards making the conflict.
well, however, I think that if Binance did that, crypto users from Russia would also choose other places to exchange and Binance might lose quite a bit of users. I think this is the right move from Binance.
It's not going to be a big loss if binance blocked Russian users because they have a million users around the world but binance didn't do it not because they are afraid to lose a small percent of their income but because they are showing how neutral they are. Don't worry binance, good things are soon going to happen with you as lots are impressed by this move you have done.
