i guess bybit is one of the emerging ones. But there are old players like bitfinex n bitstamp who are built up on solid grounds. As far as my opinion i believe binance will not survive the attack by US government. Sooner or later they will put it down. It could happen tomorrow or in 5 years no one knows but yes it will definately happen with binance. So im staying away from them and would suggest the same to others.
Bybit is emerging now and will definitely continue growing till next year but there must be exchanges that are more leading than them. About that two old crypto exchanges you mentioned. I don't know if they are still existing now, as I think I've heard a negative news about them last time. But If ever they are still alive, we also/still don't know if they will perform much better next year.
About Binance, I think they are still here with us. It's a sign that they are doing their best to survive. Besides this wasn't the first attack they have received. That is how strong they are. I guess they will still take the lead next year. If ever they are closing down, they will still give an early warning, for their users to withdraw their funds. So why worry?
