That's certainly true, mate. It's all about adoption instead of technological superiority. A cryptocurrency can have as many shiny features as developers want to, but without adoption, it won't go anywhere. Binance's blockchain network has a slight advantage over Polkadot as the company has all the funding needed to keep the project going for years to come. Being the world's biggest cryptocurrency exchange brings its benefits. Polkadot's place on the market might not last for long if hype goes all the way down the drain. Decentralized application (dApp) developers will be the ones who'll decide which platform to use for their own creations. The only downside about Binance Smart Chain is its utterly-centralized nature. Yet, it's growing at a steady rate as new dApps are built on the platform.

Nonetheless, I think both BNB and DOT are "neck and neck" when it comes to providing fast, scalable smart contracts for the world. Technically-speaking, both of these chains are far superior than ETH itself. But it's yet the time where ETH alternatives haven't proven themselves to be a real contender against Ethereum. As long as ETH remains as the "King of Smart Contracts", these aforementioned chains will only become a niche in the long run. At least, they're open source allowing existing projects to copy competitors' features in order to make the blockchain/crypto land a better place. Just my thoughts
