Who are the nearest competitors to Binance?
What are their near-future plans?
Before it was Coinbase, Bitfinex Bitstamp and even Kraken in 2017. I speculate that time that Binance's volume is around 10% but surges up to 50% in 2018-2019. https://techcrunch.com/2019/04/17/coinbase-launches-in-11-countries-with-crypto-to-crypto-conversions-only/. And since Binance started this whole IEO hype, lots of exchanges are also following that path. And with Binance DEX, they really leave the competition behind.
At the moment it is difficult to take any of those names you mentioned as serious competitors to Binance dominance.
The future will be different but for now Binance looks way head of any competitor out there.
