That's certainly true, mate. There were popular exchanges that took the crypto world by storm before Binance's launch. The main reason Binance is the biggest cryptocurrency exchange nowadays is because it's been always the main innovator in the space. By adopting the latest technologies and features, it has been able to stay on top of other exchanges worldwide. Even with recent regulations by the US, Binance will offer trading services to US customers by complying with every law. In contrast, some crypto exchanges have closed their services for US customers as they're not able to comply with existent regulations. By doing this, they'll obtain a lesser amount of users than Binance.
Given how big Binance has become even after a few years of inception, it's known to be a monopoly nowadays. No other prominent crypto exchange (like Coinbase and Bittrex) have been able to keep up with Binance as it offers the most trading pairs within the crypto space. Now, with the new Binance DEX and Binance Chain, its popularity will soar towards new heights. Projects that used to operate within the Ethereum blockchain, might switch to Binance Chain because of its unparalleled speeds and low costs. If this happens, then Binance will not only become the leader of crypto trades but also it'll become the leader of ICOs, and IEOs.
Nonetheless, Binance's monopoly may not last long if people start using other alternative crypto exchanges. With the rise of atomic swaps and decentralized exchanges, Binance's dominance within the crypto market may decline within the long term. Despite this, Binance's success will be largely determined by how many people use/support it. Just my opinion
